Answer:
cos A = 12/13 = 0.9231
(angle A = 22.62°)
Step-by-step explanation:
cos A = 12/13 = 0.9231
Answer:
its c, y = one eighthx2 + 1
Step-by-step explanation:
It is (c) NML
Because MN and ML is the vertex and the point meeting is M which is the angle.
The M is the angle because the common letter of both vertex is the letter M
Answer:
a = 50
Step-by-step explanation:
From the introduction, you know that the area is 3a^2
You also know that it is 7500 square feet. \
So the two must be equal
3a^2 = 7500 Divide by 3
a^2 = 7500/3
a^2 = 2500
The square root of 2500 is 50
sqrt(a^2) = sqrt(2500)
a = 50
Answer:

Step-by-step explanation:
Triangle

Semicircle

because both semicircle are the same just multiply by 2

Now add all together
