He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.
The answer to the question
You would divide the cheetahs distance which is 300 feet by the cheetahs time which is 2.92 seconds
distance÷time
300÷2.92= 102.7 seconds or 103 seconds if you round up
the cheetahs speed is 102.7 seconds or 103 seconds
Answer:
Step-by-step explanation:
hello :
(5y + 6)2 = 24 means : 5y+6 = √24 or 5y+6 = - √24
5y = - 6+√24 or : 5y = - 6-√24
y = (- 6+√24)/5 or y = (- 6-√24)/5
