Question

if two triangle of a triangle are 60degree and 70degree then third angle is (a) 30 (b) 70 (c) 60 (d) 50​

Answer 1

Answer:

we know that

the sum of all angles in triangle =180°

A + B + C = 180°

60 + 70 + C = 180°

C = 180 - 130

C=50

Answer 2

Answer:

Solution:-

Let third angle be x

We know that sum of all angles in triangle is 180°

According to question:-

60° + 70° + x = 180°

130° + x = 180°

x = 180° - 130°

x = 50°

D Option is correct.
