Question

find the measure of the other interior opposite angle of a triangle whose measure of the exterior angle and one interior opposite angle are respectively 120° and 50°​

Answer 1

Answer:70°

Step-by-step explanation:

since the sum of interior opposite angles of a triangle=exterior angle

Let interior opposite angle be x

Therefore

x+50°=120°

x=120°-50°

x=70°

Answer 2

Answer:

sum of interior opposite angles = exterior angle

Let the interior angle be X

X + 50° = 120°

X = 120 -- 50

=70°
