angles of the triangle. please answer fast​

Answer 1

Step-by-step explanation:

Given :-

One angle = Sum of other two angles

Solution :-

Let,

1st angle - ∠A

2nd angle - ∠B

3rd angle - ∠C

---------------------

∠A + ∠B = ∠C  -- Given

---------------------

We know that,

∠A + ∠B + ∠C = 180°

→ ∠C + ( ∠A + ∠B ) = 180°

→ ∠C + ∠C = 180°

→ 2∠C = 180°

→ ∠C = 180/2

→ ∠C = 90°

------------------

∠C = 90°
