Answer:
A) m∠3 + m∠4 = 180
Step-by-step explanation:
Both angles make a straight line which has an angle of 180.
This creates a right triangle. One leg of the triangle is 25 feet and the other is 10 feet. To find the length of the ladder, we must use Pythagorean theorem.
a = 25
b = 10
c = ?
(25)^2 + (10)^2 = c^2. Square all the terms to the left of the equation and add them together.
725 = c^2. Take the square root of each side.
c = 26.93 feet.
The ladder needs to be 26.93 feet tall.

Answer:
The answer is A
Step-by-step explanation:
I'm good at factoring lol
The radius is half of the diameter.
9/2=4.5
The radius is 4.5 feet.
Hope this helps!
