I need help with angles
Answer:
1. ∠CFD = 28°
2. ∠RPQ = 53°
Step-by-step explanation:
For the first one:
∠CFD and ∠DFE are angles on a straight line
Angles on a straight line add up to equal 180
That being said we can find the missing angle (∠CFD) by subtracting the given angle measure (152°) from 180
so ∠CFD = 180 - 152
180 - 152 = 28
Hence, ∠CFD = 28°
For the second one:
Complementary angles have a sum of 90°
If ∠RPQ and ∠SPR are complementary angles we can find the missing angle ( ∠RPQ in this case ) by subtract the given angle measure ( 37° ) from 90
so ∠RPQ = 90 - 37
90 - 37 = 53
Hence , ∠RPQ = 53°

Answer:
10. y=102,
11. x=103
12. x=145
Step-by-step explanation:
10.) 120+85+53+y=360
y+258=360
y=102,
11.) 117+100+105+115+x=540
x+437=540
x=103,
12.) 129+116+120+125+135+130+x=900
755+x=900
x=145
Answer:
10.) 102 11.) 103 12.) 145
Step-by-step explanation:
I am assuming you need help on all three questions.
10.) This shape, a trapezoid, has 4 angles. Therefore these angles are going to all add up to 360 degrees.
To solve... 360 - 120 - 85 - 53 = 102
OR...
120 + 85 + 53 = 258 then... 360 - 258 = 102
11.)This shape, a pentagon, has 5 angles. Therefore these angles are going to all add up to 540 degrees.
To solve... 540 - 117 - 100 - 105 - 115 = 103
OR...
117 + 100 + 105 + 115 = 437 then 540 - 437 = 103
12.)This shape, a heptagon, has 7 angles. Therefore these angles are going to all add up to 900 degrees.
To solve... 900 - 116 - 120 - 129 - 130 - 135 - 125 = 145
OR...
116 + 120 + 129 + 130 + 135 + 125 = then... 900 - 755 = 145

I don't know how to do this. Any help?
Answer:
cos 37=x/b (second one)
sin 37= a/b (third one)
tan 37=a/x (sixth one)
Step-by-step explanation:
Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.
The volume of a sphere depends on its radius, so the volume is a function of the radius. If this function is called V(r), use the formula below to compute V(4), the volume of a sphere with a radius of 4 units.

At the math store, one circle costs one amount, and each square costs another amount. 5 circles plus one square is 20 cents. How much would 12 circles plus 5 squares cost?
Answer: 61 cents
Step-by-step explanation:
Let’s assume a circle is X and a square is Y.
The problem states:
5x + 1y = 20
2x + 3y = 21
Taking the 1st equation we can see that
1y = 20-5x which is the same as
y = 20–5x
If we replace y in the 2nd equation with the above we get:
2x + 3(20–5x) = 21
which is the same as
2x + 60 - 15x = 21
we can rearrange to get
2x -15x = 21 -60
which is the same as:
-13x = -39
therefore x = -39/-13 or
x = 3
We can then calculate y
If y = 20–5x, then y = 20 -15
There y = 5
So to answer you question, 12 circles plus 5 squares =
12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents
hope this helps
What is the circumference of a circle having a radius of 56 mm
Answer:
The circumference is 351.68 millimeters or 352 millimeters.
Step-by-step explanation:
The formula to find the circumference of circle is 2 * pi * radius.
Applying Circumference Formula: 2 * 3.14 * 56 = 351.68 millimeters.
If you need to round to the nearest hundredth, the answer would be
352 millimeters.
I think this is correct, please don't hate me if I'm wrong. ;D
