A.50

B.60

C.70​

Answer 1

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

Answer 2

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°

$\therefore \sf \pink{The \: other \: angle \: is } \: \blue{ \: 60°}$
