Question

If two angles of a triangle are 45° and 75° .find the third angle​

Answer 1

Answer:

Two angles=45° and 75°

Sum of angles of triangle=180°

So, 45°+75°+third angle=180°

120°+ third angle=180°

Third angle=180°-120°=60°

So third angle is 60°

Answer 2

Answer:

HEY MATE HERE IS YOUR ANSWER

Let third angle be x⁰

angle sum property of triangle = 180⁰

=> 45⁰ + 75⁰ + x⁰ = 180⁰

=> 120⁰ + x⁰ = 180⁰

=> x⁰ = 180⁰ - 120⁰

=> x⁰ = 60⁰

Therefore third angle of triangle = 60⁰
