Answer:
x = 65
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
40 + x + 77 + 2x + 45 = 360
3x + 165 = 360 . . . . simplify
x + 55 = 120 . . . . . . divide by 3
x = 65 . . . . . . . . . . . subtract 55
Part A is found by solving the equation for t
Answer is 1 second
Part B
Rewrites in vertex form Thid gives
-16(t+5/8)^2 + 25/4 -4
= -16(t+5/8)^2 + 2 1/4
