A golf ball is struck by a 60-degree golf club at an initial velocity of 9898 feet per second. The height of the golf ball in f
eet is given by the quadratic function h left parenthesis x right parenthesis equals negative StartFraction 16 x squared Over left parenthesis 49 right parenthesis squared EndFraction plus StartFraction 84.9 Over 49 EndFraction xh(x)=− 16x2 (49)2+ 84.9 49x, where x is the horizontal distance of the golf ball from the point of impact. What is the horizontal distance of the golf ball from the point of impact when the ball is at its maximum height? What is the maximum height obtained by the golf ball?

If the value of x is 10. Then the measure of angle ∠COB will be 56°.
<h3>What is an angle?</h3>The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Given that A, O, and B lie on a straight line segment.
Then they make a linear angle that is 180 degrees.
Then we have
∠AOC + ∠COD + ∠DOB = 180
(3x + 94) + (x + 30) + (2x - 4) = 180
6x + 120 = 180
6x = 60
x = 10
Then the measure of angle ∠COB will be
∠COB = ∠COD + ∠DOB
∠COB = (x + 30) + (2x - 4)
∠COB = (10 + 30) + (20 - 4)
∠COB = 40 + 16
∠COB = 56°
