Question

each of the two equal angles of an isosceles triangle is twice the third angle find the angles of the triangle

Answer 1

Heya mate,Here is ur answer

Let the third angle be x.

A/Q

Equal angles =2x

By Sum angle property of a ∆

angle A+Angle B+Angle C=180°

x+2x+2x=180°

5x=180°

$x = \frac{180}{5}$

x=36

So angle A=36°

Angle B=2×36

=72°

Angle C=2×36

=72°

Answer 2

let 3rd angle be x
the the two equal angles will be both 2x
now,
we know that
2x + 2x + x = 180
5x =180
x. =180/5
x. =36


1st angle = 2x =2×36 = 72
2nd angle = 2x = 2×36 = 72
3rd angle = x = 36
