Find the measure of angle CKJ if the measure of angle LKC is x + 96, the measure of angle LKJ is 131 degrees, and the measure of
angle CKJ is x + 53.
1 answer:
Answer:
The measure of angle CKJ is 44°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠LKJ=m∠LKC+m∠CKJ ----> by addition angle postulate
substitute the given values
solve for x
<em>Find the measure of angle CKJ</em>
m∠CKJ=(x+53)°
substitute the value of x
m∠CKJ=(-9+53)=44°

Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.
