Answer:
x = 8
Step-by-step explanation:
Δ RST is equiangular since all 3 sides are congruent, thus
Each angle in the triangle is 60° , then
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8

Answer: The height of hill is 125 feet.
Step-by-step explanation:
Given that velocity of the rollercoaster is
Where, is initial velocity and h is height from top of hill.
and v is velocity at height h.
Initial Velocity is 10feet/sec at top of hill.
Also, Velocity at bottom of the hill is 90feet/sec.
Therefore, the value of h at top of the hill is h=0 and value of h at bottom of the hill is h=h
8100=100+64h
8000=64h
h=125 feets.
Thus, The height of hill is 125 feet.
D.180+x=7x
x-7x=-180
-6x=-180
x=180/6
x=30 pounds
180+30=210
