Please try to solve i know you are smart so please solve this

Answer 1

1. x+10+x+x+20=180(straight angle)
3x=180-30=150
x=50°
angles 60°, 50°, 70°
2. a+b+4b+2c+75=360°(complete angle)
a+5b+2c=360-75=285°
from the figure
a=4b then b=a/4___(2)
2c=b+75
=>b-2c=-75___(3)
from (1) and (2)
4b+5b+2c=285
9b+2c=285____(4)
from (3) and (4)
10b=210
b=210/10
b=21°
a=4b=4×21
a=84°
from (3)
21-2c=-75
-2c=-75-21=-96
c=48°
