Question

the interior angle are30 and x , the exterior angle is 70 find the value of x

Answer 1

e and c is a straight angle so angle ABC =180-70=110
the whole angles of the triangle =180 so 110+30=140
180-140=40
so,angle a =40

hope it helps

Answer 2

Answer:

We know that,

Sum of two interior opposite angles=Exterior angle

IN THIS CASE,

30°+ x=70°

x=70°-30°

x=40°

SO, 40° IS THE VALUE OF X.

Hope it will help you.
