Z=118 as vertically opposite angles are the same
x= (8x-50)
6 / (2/5) = 15
It should take the nail 15 minutes to crawl 6 meters.
Its 81 centimeters because you round 5 and over. So nearest centimeter means 2 whole numbers which is 81
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
