Answer 2

Answer:

If 1:1:2 is the ratio of angles of a triangle, then its largest angle is 90°
Step-by-step explanation:

Given

Ratio of three angles of the triangle = 1 : 1 : 2

That is if one angle is x, then others are x and 2x respectively.

The sum of angles of the triangle is 180°

That is,

x + x + 2x = 180°

4x = 180°

x = 180/4 = 45°

So, the angles of the triangle are

x = 45°
x = 45°
2x = 45*2 = 90°

Therefore, the angles are 45°, 45° and 90°

So, the largest angel is 90°
