Question

in a pair of parallel lines the measurement of co interior angles are (2x +45)° and 7x -9) ° find the angles

Answer 1

Answer:

x= 16°

2x+45= 2(16)+45= 67

7x-9 = 7(16) -9= 103°

Step-by-step explanation:

sum of co interior angles =180

(2x+45+(7x-9)=180°

2x + 7x + 45 - 9 = 180°

9x + 36 = 180°

9x = 144°

x = 16°
