Answer:
80.5°
Step-by-step explanation:
The applicable trig function is the tangent.
Tan = Opposite/Adjacent
In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...
tan(α) = 324/54
The value of the angle with this tangent is found using the arctangent function:
α = arctan(324/54) ≈ 80.5°
She should set her binoculars to 80.5°.
Answer:
(5,3) and (10,6)
Step-by-step explanation:
V = S*h
h = V/S = 250*pi / 50*pi = 5 m
<em>9 - 4(2p - 1) =45</em>
<em>5(2p - 1) = 45</em>
<em>10p - 5 = 45</em>
<em>10p = 45 + 5</em>
<em>10p = 50</em>
<em>p = 50/10</em>
<em>p =5 (ans)</em>
