Given : y = 8 - 9x
(a) we need to find value of y when x = 2
substituting x = 2 in y = 8 -9x , we get :
y = 8 - 9(2)
y = 8 - 18
y = -10
(b) we need to find value of y when x = 0
substituting x = 0 in y = 8 -9x , we get :
y = 8 - 9(0)
y = 8 - 0
y = 8
-95 degrees, doing this by adding 360 to the original to give a smaller angle aka reference angle
hope this helps
Answer:
20.8 ft²
Step-by-step explanation:
area = (ab sin C)/2
area = (6 ft × 8 ft × sin 60°)/2
area = 20.8 ft²
