x + 15 + 3x - 17 + 90= 180 4x + 88= 180 4x = 92 x= 23

This is a right angle, and we know that a right angle is equal to 90 degrees; therefore,(x+15)+(3x-17)=90Combine like terms:4x-2=90Add 24x=92x=23To test this solution for accuracy, plug in 23 for all the x values in the equation, and if the equation yields 90, you are correct. In this case, 23 is the correct value for x :)
