Solve a/-6+ 8 = 12. a =

a/(-6)+8 = 12 // - 12

a/(-6)-12+8 = 0

-1/6*a-4 = 0 // + 4

-1/6*a = 4 // : -1/6

a = 4/(-1/6)

a = -24

a = -24

Step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
