Question

5. The measure of two angles of a triangle are 50° and 80°. Find the measure
of the third angle.​

Answer 1

Answer:

50°

Step-by-step explanation:

50+80=130

sum of triangle is 180

180-130 =50

Answer 2

Answer:

Measure of third angle of the triangle = 50°

Step-by-step explanation:

First angle of the triangle = 50°

Second angle of the triangle = 80°

Let the third angle of the triangle = x

Sum of all angles of a triangle = 180° (By angle sum property)

According to question ,

50 + 80 + x = 180

= 130 + x = 180

= x = 180 - 130

= x = 50°

Thus , the measure of third angle of a triangle is 50°
