Answer:
m∠P=140°
Step-by-step explanation:
Given:
∠P and ∠Q are supplementary angles.
The measure of angle P is five less than four times the measure of angle Q.
To find m∠P
Solution:
The measure of angle P can be given as:
A)
And
B) [Definition of supplementary angles]
Substituting equation A into B.
Solving for
Using distribution:
Simplifying by combining like terms.
Adding 20 to both sides.
Dividing both sides by 5.
Substituting in equation B.
Subtracting both sides by 40.
Thus, we have:
m∠P=140° (Answer)
Answer:
Step-by-step explanation:
Known facts:
- the ball dropped from a height of 64 feet
- function
First question:
- the ball hits the ground when h(t) = 0, thus we get the equation
So the ball hits the ground in 2s
Second question
- to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28
So the ball hits the ground in 1.5s
Hope that helps!
