Answer:
Step-by-step explanation:
.155 would be the decimal. 58-49 is 9. 9/58 to find the decimal of .155. then multiply by 100 to get 15.5% or 16%
16%
x = 19
Assuming all angle measures are in degrees, the sum of them is 180:
(3x +16) +(4x -15) +(2x +8) = 180
9x +9 = 180 . . . . collect terms
x + 1 = 20 . . . . . . divide by 9
x = 19 . . . . . . . . . .subtract 1
The value of x is 19.
