Question

Each of the two equal angles of an isosceles triangle is twice the third angle.Find the angles of the tringle

Answer 1

Step-by-step explanation:

Let the third angle be x

Then the equal angles = 2x

Sum of all angles of a triangle are equal to 180°

$x + 2x + 2x = 180$

$5x = 180 \\ x = 180 \div 5 \\ x = 36$

$2x = 2 \times 36 = 72$

So, the angles of the triangle are 72°, 72° and 36°

Answer 2

Step-by-step explanation:

let the third angle be x

therefore equal angles are 2x and 2x

by angle sum property of triangle

5x = 180

x= 36

so two equal angles are 72 and 72

and third angle is 36
