SOMEONE ANSWER PLEASE!!

(Two office buildings are 51 m apart. The height of the taller building is 207 m. The angle of depression from the top of the ta

Sholpan [36]

See the attached figure to better understand the problem

we know that

in the triangle ABC
tan 15=AC/BC--------> AC=BC*tan 15
BC=51 m
AC=51*tan 15------> AC=13.67 m

the height of the shorter building=207-AC----> 207-13.67----> 193.33 m
the height of the shorter building=193 m

the answer Part a) is
the height of the shorter building is 193 m

Part b) how does the angle of depression from the top of the taller building relate to the angle of elevation from the top of the shorter building

we know that

the angle of depression is equals to the angle of elevation
so

the answers are
A:They are congruent
D:They are alternate interior angles

Short Answer: 150

Remark
You have to use two facts.
1. The central angle = 2 * the angle at B
2. The central angle = the arc angle.

Given
angle at B = 75 degrees.

Calculate the central angle
Central angle = 2 * angle at B
Central angle = 2 * 75
Central angle = 150

Conclusion
The arc angle = Central angle
The arc angle = 150 degrees.
