Answer:

∠7=120 degrees, ∠8=60 degrees.

Step-by-step explanation:

Since the roads are parallel lines, we can say that angle 4 is equal to 60 degrees, since a line is 180 degrees and 180-120=60.

We can then say that with the corresponding angles theorem, angle 4 is equal to angle 8. Since angle 7 is on the same line, and lines are 180 degrees, we can say that angle 7 is 180-60, or 120 degrees.

Goshia [24]

Answer:

height of the building is 12.99 feet.

Step-by-step explanation:

given, try to analyse:

ladder 15 feet long.
60 degree angle to the ground.

the height of the building is opposite to the angle 60° and given hypotenuse, the ladder of 15 feet long.

using sine rule:

$sin(x) = \frac{opposite}{hypotenuse}$

$sin(60) = \frac{opposite}{15}$

$opposite = sin(60) *15$

$opposite = 12.99feet$

Therefore the height of the building is 12.99 feet.
