Question

please provide me answer with explanation

Answer 1

Answer:

3x°+(2x+5)° = 90°

5x° + 5° = 90°

5x° = 85°

x = 17°

Answer 2

3x + ( 2x + 5 ) + 90 = 180                    

( sum of the angles on a straight line is equal to 180 )

5x + 95 = 180

5x = 180 - 95

5x = 85

x = 85/5

x = 17

( 1 ) 17 is the correct answer
