Answer:
w = 13
Step-by-step explanation:
Right angle: 90°
Write an equation:
(4w + 5)° + 33° = 90°
Solve for w.
(4w + 5)° = 90° - 33°
(4w + 5)° = 57°
You can take away the brackets.
4w + 5 = 57
Isolate w.
4w = 57 - 5
4w = 52
w = 52 ÷ 4
w = 13
I hope this helps!

that is it
h(t) = 80t - 16t²
Ground level is h(0) = 0
We want to solve for t:
h(t)= 0
80t - 16t² = 0
16t(5 - t) = 0
t = 0 or t = 5
