Answer:
m∠1 = 71°
Step-by-step explanation:
Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.
Set the measures of the two angles equal to 90°

Combine like terms

Solve for x

Plug the value of 'x' back into the given equation for the measure of angle 1

m∠1 = 71°
2,920
8 hours multiply by 365 equals 2,920 hours
It's a 3rd degree polynomial judging by the shape. Use the 3 factored zeros of x=-1,0,2 to get x(x+1)(x-2)
multiply this out to get
