Benjamin is trying to find the height of a radio antenna on the roof of a local building. He stands at a horizontal distance of 25 meters from the building. The angle of
elevation from his eyes to the roof (point A) is 28°, and the angle of elevation from
his eyes to the top of the antenna (point B) is 40°. If his eyes are 1.52 meters from
the ground, find the height of the antenna (the distance from point A to point B).
Round your answer to the nearest meter if necessary.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

b.-4 units

all you   do is count how many times you move

yes.. it's proven to be 36.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
