Find length FD
FD is Opposite
BD adjacent
O + A is Toa
Tan20 = o/9
x9
9 x Tan20 = o
O = 3.2757.... (ans)
Opposite/ FD is 3.28cm to 2.p.d
Draw diagonal line from A to D & find its length - that's the hypotenuse of a right-angle created
Use Pythagoras Theorem
a^2 + b^2 = c^2
25^2 + 9^2 = c^2
Square root both sides to get c
C = root 25^2 + 9^2
= root 706
= 26.57066...(ans)
AD is 26.57cm
Now create another right-angle triangle A to F to D back to A.
Label dimensions found such as the Length of AD to be 26.57.. Plus, FD to be 3.28.
Use trig for angel FAD:
Opposite of triangle is 3.28
Adjacent is 26.57
So, OA means Toa, but we're after an angle & have to use tan inverse instead.
Tan-1 (3.28/26.57) = 7.0374..
So, the angle is 7.04 degrees.
(ans) - ignore, I did use rounded figures in my ans, I was originally not going to, but I did.
Hope this helps!

Answers
The length 11 cm is closer to the length of the diagonal of this square in centimeters.
How to determine the value of x?The equation is given as:
x^2 = 132
Take the square root of both sides
x = √132
Evaluate the square root
x = 11.49

Our basketball team won 60 percent of their games. If they lost 8 games, how many games did they play altogether?
Answers
Answer:
they played 20 games together
Step-by-step explanation:
use percentages
Let x be the number of total games.
If 60% is won games then 40% is lost games.
(8/x)*100 = 40
8/x = 4/10
80 = 4x
X = 80/4
Therefore the number of games is 20
They lost 8 games. So those 8 games accounts for 40% of all the matches they played.
8 games = 40%
(divide by 8)
1 game = 5%
To get 100% ie the total number of games played you do 5% x 20
So you also do 1 x 20 to get 20 games played in total.

At Shannon's Pancake House there are 228 dirty coffee mugs and 247 clean coffee mugs. What percentage of the coffee mugs at the pancake house are dirty? Write your answer using a percent sign
Answers
Answer:
48%
Step-by-step explanation:
First, we need to add the amounts together to be able to see what percent of all the cups are dirty. (228 + 247 = 475). Now we can find one percent of 475 we can do this by moving the decimal point two to the left. (4.75). so If 4.75 is 1% we can multiply 4.75 until we get 228.
4.75 x 20 = 95.
4.75 x 40 = 190
4.75 x 45 = 213.75
4.75 x 50 = 237.5
4.75 x 48 = 228
Since every time we multiplied by 1 more we went up 1%. We multiplied by 48 so 48%.

Answer:
Carter family = 25 hours
Davis family = 31 hours
Step-by-step explanation:
Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.
So combined:
x + y = 45 hours
and we are also told that:
40x + 15y = 1300 L
So we can do simultaneous equations to solve the problem.
With some rearranging, we can figure out that:
y= 45 - x
and by substituting that into the second equation:
40x + 15 (45 -x) = 40x + 675 - 15x = 1300L
25x = 1300 - 675
25x = 625
x = 25 = hours that the Carter family used their sprinkler
and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:
25 + y = 56
y = 31
The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

The image shows a circle with center (4,6) and radius 10 units.
Answers
A circle is a curve sketched out by a point moving in a plane. The point that lies on the circle is (-4, 12), (-6, 6), and (4, 16).
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The simple way to do such questions is to make the given circle and plot the points on the graph. As shown below.
The other way to do the question is to find the distance between the centre point of the circle and the point if it is equal to the radius of the circle, the point will lie on the circle, otherwise not.
The formula to find the distance between the two points on a graph is,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence, the point that lies on the circle is (-4, 12), (-6, 6), and (4, 16).
