Step-by-step explanation:

The relevant trig relation is ...

Cos = Adjacent/Hypotenuse

cos(x) = 8/10 = 0.8

The inverse trig function is used to find the angle:

x = arccos(0.8) ≈ 36.9°

Solve the equation for the given variable. justify each step.

s344n2d4d5 [400]

Answer: y= $\frac{5-9x}{2}$

s=-30+10t

Step-by-step explanation:

9x + 2y = 5; y

9x-9x+2y = 5-9x

2y=5-9x

y= $\frac{5-9x}{2}$

1/15s - 2/3t = -2; s

(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15

s - 30/3 t=-30

s-10t=-30

s=-30+10t
