Answer:
4.2 ft
Step-by-step explanation:
Reference angle = 77°
Opposite side = DE = x
Hypotenuse = CD = 4.3 ft
Apply the trigonometric function of sine. Thus:
Sin 77 = opp/hyp
Sin 77 = x/4.3
Multiply both sides by 4.3
4.3 × sin 77 = x
x = 4.2 ft (nearest tenth)
Answer: y = 5/8x + 0.5
Step-by-step explanation:
5/8 is the slope if you could 5 up and 8 to the side
slope form is y=mx+b
y = 5/8x + 0.5
