Answer:
y = -1/5x + 8
Step-by-step explanation:
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:
124°+95°+124°+54°+R = 180°
R = 143°
Answer:
the oldest is 31 years old, the youngest is 15.5 years old, and the middle is 10.5 years old
Step-by-step explanation:
First you take the two halves from 10.5 and 15.5 and add the two halves to get 1. So you would make an equation. The one I used was (10+1)=(15+31)= 57
