Answer:
105.5 ft
Step-by-step explanation:
The tangent ratio is the ratio of the side opposite an angle to the adjacent side in a right triangle. Here, the side opposite the angle is the tower height, and the adjacent side is the distance to the tower. Then the appropriate relationship is ...
tan(38°) = (tower height)/(135 ft)
Multiplying by the denominator gives ...
tower height = (135 ft)·tan(38°) ≈ 105.473 ft
The height of the tower is about 105.5 feet.
Answer:
139
Step-by-step explanation:
It is b 70 because in a quadrilateral the angles have to equal 360 and 85 + 150 + 55 equals 290 360 - 290 is 70
