Question

14. If 3x + 18º and 2x + 25° are supplementary, find the value of x.​

Answer 1

Answer:

3x+18 + 2x+25 = 180

5x +43 = 180

5x = 180-43

5x = 137

x= 137/5

x= 27.4°

Answer 2

Answ

Step-by-step explanation:

( 3x + 18 ) + ( 2x + 25 ) = 180

3x + 18 + 2x + 25 = 180

5x + 43 = 180

5x = 180 - 43

5x = 137

x = 137/5

x = 27.4
