Answer:
We have not write the question properly . so I write the point .
Step-by-step explanation:
18-6=12
4.5 the finest in a wide range is to make the best choice of
m∠CPD = 129.75°
m∠APD + m∠APB = 180 since the angles are supplementary
x + 1 + 3x - 18 = 180
4x - 17 = 180
4x = 197
x = 49.25
m∠APB = 3(49.25) - 18 = 129.75
m∠APB = m∠CPD because the angles are vertical angles
I dont know if this will help or not but
