I will.. but please add some points...

because this one looks like alot of hardwork

for 5 points..

don't mind :-(

Answer 2

Step-by-step explanation:

2) it's clear that 2 vertices are equal so y=70°

and by exterior angle property 2 opposit anes are equal to an exterior angle then the answer of x is 140 °

3)by angle sum property 4x+3x+2x=180°

then 9x=180°

=x=180/9 or 20°

therefor x=20°

then 4x= 4×20

3x=3×20

2x=2×20

therefor all three angles are 80°,60°,40° respectively

by lenior pair property 20°+y=180°

Therefor y=180-20

y=160°
