Answer:
Angle B is 54º.
Step-by-step explanation:
First, find <em>x</em>. Since angle A and angle B are supplementary angles, they add up to 180º.
(7<em>x</em> + 7)º + (4<em>x</em> - 14)º = 180º.
11<em>x</em> - 7 = 180
11x = 187
<em>x</em> = 17.
Now, substitute 17 for <em>x</em> in angle B's equation, (4<em>x</em> - 14).
4(17) - 14
= 68 - 14
= 54º

Answer:
45 meters
Step-by-step explanation:
The equation is given in vertex form:
h(t) = a(t -b)^2 +c
where (b, c) is the vertex (maximum).
The values of the parameters are ...
a = -5, b = 3, c = 45
Then the maximum height is (time, height) = (3, 45).
The maximum height of the ball is 45 meters.
