Question 1:Look at the first attached image.
We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.
Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.
![51*tan(15)](https://tex.z-dn.net/?f=51%2Atan%2815%29)
![\approx 14](https://tex.z-dn.net/?f=%5Capprox%2014)
Now, subtract that from 207 to get the height of the smaller building.
![207-14=193](https://tex.z-dn.net/?f=207-14%3D193)
That's your answer.
Question 2:
The angle of elevation is congruent to the angle of depression because they are alternate interior angles.
Thus, you can choose the 1st and 4th choices as your answer.
Question 3:Look at the second attached image.
Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.
![3x+1=2(x+8)](https://tex.z-dn.net/?f=3x%2B1%3D2%28x%2B8%29)
Distributive property
![3x+1=2x+16](https://tex.z-dn.net/?f=3x%2B1%3D2x%2B16)
Subtract both sides by 1 and 2x
![x=15](https://tex.z-dn.net/?f=x%3D15)
Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.
The third choice is your answer. Hope this helps! :)

Given:
The sequence is defined as "triple v, then subtract 7 from the result".
To find:
The expression for the given sequence.
Solution:
Triple v means 3 times of v, i.e., 3v.
So, the result is 3v.
Then subtract 7 from the result. So, the expression for the sequence is
![3v-7](https://tex.z-dn.net/?f=3v-7)
Therefore, the required expression is
