Applying the cosine ratio, the measure of angle C in the given image, to the nearest whole degree, is: 77°.
<h3>What is the Cosine Ratio?</h3>
The cosine ratio is given as, cos ∅ = adjacent side/hypotenuse side of a right triangle.
Using the cosine ratio, we have:
cos C = 2/9
C = cos^(-1)(2/9)
C ≈ 77 degrees.

Answer:
x=0, - 9
Step-by-step explanation:
x^2+9x=0
x(x+9)=0
x=0 or x=-9
Answer:
140 feet
Step-by-step explanation:
If the first time she dropped the ball was from 160 feet then the second time she dropped the ball is would bounce back up 80 feet. The third time it would bounce 40 feet. And the 4th time it would bounce 20 feet
So the total distance the ball traveled from the first time it hit the ground is 140 feet
