To find the value of 
, we need to isolate it on one side of the equation. Add 
to both sides of the equation, then multiply both sides of the equation by 
.
Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula 
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put 
So,
Put t = 2.62 s in the equation of height. So,
So, the maximum height of the rock is 110.24 m.
According to google, the red marks mean those two lines are the same length. If that's the case, we know that x is the angle in both corners of the lower triangle. We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40. That leaves 140 for the rest. Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees. It is divided in two parts, the lower one of which we just found to be 20. So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees
