Question

In a triangle ABC , angle A=50° angle b=70°. what is the measure of third angle .
with solution.

Answer 1

As we know , in any ∆ sum of all angles is 180°
So in given ∆
A+B+C=180°
using the given angles
50°+70°+C=180°
C→60°

hope you are helped in your homework

Answer 2

hey friend! here is your answer-
In a triangle ABC,angle A=50°,angle b=70.what is the measure of third angle.
sum of triangle abc- 180 degrees.
to find the third side. 
let the third side be x degrees.
so, 70+50+x= 180
      120+x=180
now 120 will go to that side so here it is plus there it will be minus.
so, x= 180-120
      x=60 degrees.     
therefore, the third side is 60 degrees.
hope it helps. please mark it brainliest.
