Answer:
i really dont understand is that the whole oimg??
Step-by-step explanation:
Answer: 72°, 108°, 108°
<u>Step-by-step explanation:</u>
Vertical angles are congruent (equal) so if one angle is 72° then its vertical angle is also 72°.
A vertical angle and its adjacent angle form a 180° angle, so the other two angles are each 180° - 72° = 108°

Plug in 30ft for L and 2310 for n so you will get 2310=7(30)(h)... h would equal 11ft
Let us assume PQ || BC.
Then, by Basic Proportionality Theorem, we get,
AP/PB = AQ/QC
=> x/(x+7) = (x-3)/(x+1)
=> x (x+1) = (x+7)(x-3)
=> x^2 + x = x^2 - 3x + 7x - 21
=> x = 4x - 21
=> -4x + x = -21
=> -3x = -21
=> 3x = 21
=> x = 21/3
=> x = 7
Therefore, for PQ||BC the value of x should be 7
