Question

please give ans with explanation​

Answer 1

Answer:

Base angles of isosceles triangle are equal.

so let the base angles=x

we know that the sum of these angles is 90

so, 2x=90

x=45

the base angles are 45 degrees.

now we use the angle sum property of triangle.

let the 3rd angle=y

so 45+45+y=180

90+y=180

y=90

so the ratio of the angles would be

90:45:45 or in the simplest form --->

2:1:1
