Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540
so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
Answer:
original: 7.069
rounded: 7.1
Step-by-step explanation:
The distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
<u>Explanation:</u>
Given:
Height, h = 75 foot
Initial velocity, u = 107 foot/sec
Equation:
h = -16t² + 107t + 75
Substituting the equation:
75 = -16t² + 107t + 75
0 = -16t² + 107t
16t² = 107t
t = 6.6875s
We know:
Distance = speed X time
d = 107 f/s X 6.6875s
d = 715.56 foot
Therefore, the distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
