Answer:
∠1 = ∠3 = ∠5 = ∠7 = 72°
∠2 = ∠4 = ∠6 = ∠8 = 180° -72° = 108°
∠13 = ∠14 = ∠15 = ∠16 = ∠17 = ∠18 = ∠19 = ∠20 = 90°
∠10 = ∠12 = 90° -72° = 18°
∠9 = ∠11 = 180° -18° = 162°

Total solar eclipses occur on a regular and predictable basis. One that could be viewed in parts of the United States occurred on March 7, 1970. The saros cycle is a period of 18 years, 11 1 3 days, and solar eclipses occur according to this cycle. For the purposes of this exercise, we ignore leap years and assume that a year is exactly 365 days. Because the saros cycle is not a whole number of days, but instead is one-third of a day longer than a day, at the end of the saros cycle, Earth will have rotated one-third revolution beyond its location at the beginning of the cycle. Thus, if a solar eclipse is viewable at a certain location, the next solar eclipse will not be. How long after March 7, 1970, will a solar eclipse again be viewable from the United States?
Answer:
Step-by-step explanation:
The previous solar eclipse occured on March 7 , 1970 .
saros cycle has duration of 18 years , 11 + 1/3 days
So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse
So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days
Date of next solar eclipse on the same spot = 1970 + 54 = 2024
7 th March + 34 days = April 10
likely date = April 10 , 2024 .

[tex]=-1+2sin\frac{C}{2}*2cos \frac{\frac{A-B}{2} +\frac{A+B}{2} }{2} cos \frac{\frac{A-B}{2} -\frac{A+B}{2} }{2} \\=-1+4sin\frac{C}{2} cos \frac{A}{2} cos\frac{-B}{2} \\=-1+4 cos \frac{A}{2} cos \frac{B}{2} sin \frac{C}{2}\\(cos(-B)=cos B)[/tex]

Describe the possible values of x.
Answer:
2 ≤ x ≤ 7
Step-by-step explanation:
Due to the triangle inequality, the sum of two sides of a triangle must be greater than or equal to the remaining side.
Therefore,
5+7 ≥ 2x-2
=> 12 ≥ 2x-2
=> 14 ≥ 2x
=> 7 ≥ x
However, notice that BC + AB must be ≥ 7, So,
5 + 2x - 2 ≥ 7
=> 2x - 2 ≥ 2
=> 2x ≥ 4
=> x ≥ 2
Therefore, both bound of x have been found.
The possible values of x are 2< x < 7.
What is side length property of a triangle?In a triangle, the sum of two sides is always greater than the third side. And the difference of two sides is always less than the third side.
Given,
First side = 5
Second side = 7
Therefore, sum of first and second side = 5 + 7
= 12
Also, absolute difference of first and second side = 7 - 5
= 2
Therefore, we can write:
2 < 2x - 2 < 12
Or 4 < 2x < 14
2 < x < 7
Hence, the possible values of x are 2< x < 7.

If you deposit $600 into an account which earns 4% yearly interest compounded quarterly,
how much will be in the account after 7 years, assuming you never withdraw money from
the account? Round your answer to the nearest cent if necessary and do not include the
dollar sign.
Provide your answer below:
Answer:
4,368
Step-by-step explanation:
take 600 and add 4% to get 624
then take the 624 and multiply by 7
and the answer is 4,368
let's see what to do buddy...
_________________________________
_________________________________
Step (1)
We have 600 $ .
One year later ;
[tex]600 + (600) \times \frac{4}{100} = 600 + 24 = 624 \\ [/tex]
Now we have 624 $.
_________________________________
Step (2)
One year later :
[tex]624 + (624) \times \frac{4}{100} = 624 + 24.96 = \\ 624 + 25 = 649 [/tex]
After two years we have 649 $.
_________________________________
Step (3)
One year later :
[tex]649 + (649) \times \frac{4}{100} = 649 + 25.96 \\ 649 + 26 = 675 [/tex]
After three years we have 675 $.
_________________________________
Step (4)
One year later :
[tex]675 + (675) \times \frac{4}{100} = 675 + 27 = 702 \\ [/tex]
So after four years we have 702 $.
_________________________________
Step (5)
One year later :
[tex]702 + (702) \times \frac{4}{100} = 702 + 28.08 \\ 702 + 28 = 730 [/tex]
After five years we have 730 $.
_________________________________
Step (6)
One year later :
[tex]730 + (730) \times \frac{4}{100} = 730 + 29.20 \\ 730 + 29 = 759 [/tex]
So After six years we have 759 $.
_________________________________
Step (7)
One year later :
[tex]759 + (759) \times \frac{4}{100} = 759 + 30.36 \\ 759 + 30 = 789 [/tex]
So after seven years we have 789 $.

Hamdah wants to save $500 to buy a TV. She saves $17 each week. The amount, A (in dollars), that she still needs after w weeks is given by the following function. =Aw−50017w Answer the following questions. (a) If Hamdah still needs $211, how many weeks has she been saving? weeks (b) How much money does Hamdah still need after 5 weeks? $
Answer:
(a) 14.11 dollars (b) 204 dollars
Step-by-step explanation:
(a) 500 - 211 = 289 289 '/. 17 = 14 r:7 14.7 dollars
(b) 17 x 5 = 85 289 - 85 = 204
hope this helped :)
Answer:
If Hamdah still needs $211, she has been saving for 17 weeks(17b). Hamdah still needs $126 after 5 weeks
Step-by-step explanation:
Subtract $211 from $500, you will get $289. After you must divide $289 by 17 because Hamdah earns $17 each week, you will get 17 and that represents how many weeks she has been saving. Hamdah still needs $126 because taking the information from the last question she has $289 (289+211 equals 500, 211 is how much she needs and 289 is how much she has) so we subtract 289 from 500 and we will get 211, then you subtract the product of $17 × 5 weeks from 211 and you will get $126. So, after 5 weeks, Hamdah will still need $126.

objective: to arrange in rows with an equal number (n) of only boys or girls.
To find the maximum number (n) of boys or girls in each row, we need to find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that n divides both numbers evenly without a remainder.
We will use two methods to find the GCF of two numbers.
Factorize each number to powers of prime and locate the common factors.
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90
