Step-by-step explanation:
we are given a triangle
and we want to figure out the missing exterior angle of the triangle
in order to so
remember
the straight line theorem
therefore we get:
cancel 72° from both sides:
Alternate way:recall that,
if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles
so we acquire:
simplify addition:
