Answer 1

Answer:

Answer is 100 ina quadrilateral

Answer 2

Answer:

I can see only one question so I'll answer it

Step-by-step explanation:

First of all,

sum of total angle of quadrilateral=360°

First angle=130°

second angle=30°

angle 3 =angle 4 = x

hence,

130+30+x+x=360°

160+2x=360°

2x=200°

x=200/2°

x=100°

hence,answer is e
