Solve for x:
Зах + b = с

x= −b+c/3a

Step-by-step explanation:

3ax+b=c

3ax+b+−b=c+−b

3ax=−b+c

3ax/3a = −b+c/3a

x= −b+c/3a

congruent segments

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
