Answer:
cos P = 53 degrees
cos Q = 37 degrees
Step-by-step explanation:
cos P = 
cos P = 
cos P = 0.60
Cos-1 of 0.60 is 53.13 (round to the nearest whole number)
cos P = 53 degrees
cos Q =
cos Q = 
cos Q = 0.80
Cos of 0.80 is 36.86 (round to the nearest whole number)
cos Q = 37 degrees
To check anser:
90 + 53 + 37 = 180
180 = 180
On all sides of a triangle it’s about 7 inches
An expression for that would be s + 0.05s, or 1.05s.

You can put the 2 circles together to get 1 circle
so basically we just find
area of rectangle taht is 8ft by 18ft
and area of ciecle with disameter of 8
area rectangle=18 times 8=144 square feet
area of ciecle=pir^2
d/2=r, 8/2=4
area=pi4^2=16pi, pi=3.14 so then
50.24
toal is rectangle+circles=144+50.24=194.24 suare feet
rounded
194 square feet
