Answer 1

Answer:

90° hope it will helpful for you

Answer 2

Given,

The ABC is a right angle isosceles triangle.

To find,

The greatest angle of the ∆ABC.

Solution,

The ABC is a right angle isosceles triangle.

So, one of the angles of ∆ABC is definitely 90°.

Now, the base angles of the isosceles triangles are equal and the equal angle cannot be 90° because only two angles will sum up to the total internal angles.

Let, the equal angle = x°

(Assume, x as a variable to do the further mathematical calculations.)

Now,

90+2x = 180

2x = 90

x = 45

Now, 90°>45°

So, the biggest angle is 90°

Hence, the largest angle is 90°.
