Answer:
x = 17
∠A = 114°
Step-by-step explanation:
In the figure attached, the complete question is shown.
From the figure, we know that:
∠A = ∠B
Replacing with the expressions, we get:
6x+12 = 3x+63
6x - 3x = 63 - 12
3x = 51
x = 51/3
x = 17
∠A = 6(17)+12
∠A = 114°
First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .
Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94 seconds.
Answer in interval notation is (3, 5.94].
