Question

Find x
For this question

Answer 1

X=70+60 =130(exterior angle property)

Answer 2

the sum of the angle of a is 180.
hence, in ABC,
m/_A+m/_B+m/_C=180
70+60+m/_C=180.
130+m/_C=180 ,
m/_C=180-130 =50
m/_C=50,
m/_C+X=180 ,
50+m/_C=180 ,
M/_C=180-50=130,,
hence, X=130,,
hope this will help uh...
