Answer:
(-3,5)
Step-by-step explanation:
When you reflect over the x axis, the y value's sign changes.
So we have:
-3,5
Answer:
m∠E = 38.7°
Step-by-step explanation:
If you make a drawing it will help. What you have is a right triangle where you are given the adjacent side to ∠E and the hypotenuse.
The cosine of a angle = adjacent side/hypotenuse.
Therefore cos E = 32/41
arccos (32/41) = 38.7°
Answer:
Step-by-step explanation:
For a
2 + x = 15
x = 15 -2
x = 13
For B
x - 12 = 14
x = 12 + 14
x = 26
For C
3x = 12
x = 12/3
x = 4
Hope it helps:)
Answer:
It is 39.3
Step-by-step explanation:
You find the circumference using the formula 2πr so you get 20π.
and then you multiply that by 225/360 bc 360 is how much the whole circle is and the 225 part is the part you want to solve.
So 20π*225/360 is about 39.3
