Answer 1

Answer:

the answer is 370 ° all the three angles can be solved by supplementary angles and angle is corresponding of 130 ° this way we can solve

Answer 2

Answer:

a+b+c+d=360°

Step-by-step explanation:

b+130°=180° (linear pair)

b=50°

c+100°=180° (linear pair)

c=80°

d+70°=180°

d=110°

Now, let the angle forming a linear pair with a be x

130°+100°+70°+x=360° (Angle Sum Property of quadrilaterals)

x=60°

a+x=180° (linear pair)

a+60°=180°

a=120°

So,

a+b+c+d=?

120°+50°+80°+110°=360°

Hope it helps!!!
