8.180-65-90=25
180-80-60=40
So, 180-40-25=115.
9.(180-40)divide by 2=70
X=180-70
X=110
10.180-118=62
So, 180-62-90
=28
11.not confident yet
12.180-60=120
13. (180-66)divide by 2 =57
180-57=123
(180-123)divide by 2
=28.5
14.180-68-44=68
180-58-73=49
So,180-68-49=63
(Its the same)

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
