The equation would be 4+x 13. Subtract 4 from both sides. The four on the left would cancel out and the 13 on the right would now be a 9. Therefore, the answer is
Alright here we go First we need to find the upper angle by doing 180 - 143 = 37. Because it’s a straight line. Second we need to find angle ADC a triangle has 180 degrees, and we have 38 and 37. 180 - (38+37) = 105 then we find what the question wants: 180 - 105 = 75 degrees
