Answer:
x = 40°
Step-by-step explanation:
Reference angle = x°
Adjacent side length to reference angle = 7.2
Hypotenuse = 9.4
Apply trigonometric function CAH, which is:
Cos x = Adj/Hyp
Substitute
Cos x = 7.2/9.4
Cos x = 0.76596
x = 40° (nearest tenth)
Answer:
64
Step-by-step explanation:
Rewrite Equations
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30
y=−20
(Simplify both sides of the equation)
Answer: x=10 y=-20 (10,-20)
