Question

two angles of a triangle is 50° and 30°• find the measure of third angle of a triangle​

Answer 1

Answer:

we know that sum of all angles in a triangle is 180°

let the third angle be x

now. 50+30+x=180

80+x=180

x= 180-80

x=100°

Answer 2

Answer:

100

Step-by-step explanation:

Let angle A be 50

Let angle B be 30 and the third angle be C

Wkt..

Sum of interior angles of triangle =180

A +B+ C=180

50 + 30 + C =180

80 + c =180

C =180 - 80

C =100 degree
