Question

pls answer these questions... I'll surely mark brainliest... pls answer the question

Answer 1

7.sum of a linear pair is 180°
x+70°+60°=180°
x+130°=180°
x=180°-130°
x=50°

8.angle ADB=1/2 angle
angle ADB=1/2*100
angle ADB=50°

9.angle BAO = angle AOD=57°
parallel lines are equal.
angle QPO=angle DOP=40°
angle AOP=angle angle AOD+angle DOP
x=57°+40°
x=97°

Answer 2

7) x+70°+60°=180°[sum of adjacent angles]
x+130°=180°
x=50°

8) angle ADB=1/2 angle ACB
angle ADB=1/2*100
angle ADB=50°
