Answer:
y=130°
Step-by-step explanation:
180-(90+40)
180-130
50°
y=180°-50°
=130°
Step-by-step explanation:
Kx = u - y
Divide both sides by k
X = <u>u</u><u> </u><u>-</u><u> </u><u>y</u>
K
I think that's the answer
Hope it helps:)
U would put it into a calculator
V = x/t = 4.5 mil / 3 h = 1.5 mph
Since, v = 1.5 mph (or we can say that v is constant), distance and time vary directly and the constant of variation is 1.5 mph.
