first you set up the problem, supplementary angles equal 180 degrees so the equation should look like, 4x+x+15=180. then you solve from there by combining like terms and you should get x equal to 33

The distance s that an object falls is directly proportional to the square of the time t of the fall. If an object falls 16 feet

Lemur [1.5K]

Answer: if S is the distance, the fact that the distance is proportional to the square of the time means that S(t) = a* $t^{2}$ where a is a constant of proportionality, with units of $\frac{feet}{s^{2} }$ .

We know that S(1) = 16 feet = a*1, then a = 16 $\frac{feet}{s^{2} }$

then S(2) = 16*4 feet = 64.

and if we want to know in how much time te objet will fall 400feet, then S(t₀) = 400 feet = 16* $t₀^{2}$

so t₀ = $\sqrt{400/16}$ = 5s.
