Answer :
b 50 degrees
Explanation :
Sum of all angles of triangle = 180 degrees
First angle = 50 degrees
Second angle = 70 degrees
Let third angle be x
x + 50 + 70 = 180
x + 120 = 180
x = 180 - 120
x = 60 degrees

Step-by-step explanation:
B) 60°
QuestioN ::-
If the two angles of a traingle is 50 and 70 then the measure of third angle is
Given ::-
50° and 70°
We know ::-
Since we know measure of triangle is 180°
Formula ::-
A + B + C = 180°
AnsweR ::-
Let the other angel be x.
50 + 70 + x = 180°
=> 120 + x = 180
=> x = 180 - 120
=> x = 60°
