Martian Derivatives A package is dropped from a height of 402 feet on Mars, where
acceleration due to gravity is about 13 feet per second squared. The
equation that represents this fall is given below.
h(t)= 402 - 13(t^2)
Approximate the velocity of the falling package after 4 seconds.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
