Answer 2

Answer:

• 90° is the largest angle.

Step-by-step explanation:

According to the Question

It is given that ,

Angles of a triangle are in the ratio of 1 : 1 : 2.

Let the ratio be 1x : 1x : 2x

As we know that sum of all angles in a triangle is 180° .

Sum of angles in a triangle = 180°

substituting the value we get

→ x + x + 2x = 180°

→ 4x = 180°

→ x = 180°/4

→ x = 45°

2x = 2×45 = 90°

So, the angles are 45° , 45 ° & 90°

• Hence, the value of largest value is 90°.
