Question

Q8 Two angles of a triangle are equal and its third angle is double of the equal angle. Find the measures of the three angles of the triangle.​

Answer 1

Answer:

Let the two equal angles be x each

let the greater angle be 2x

we know sum of all interior angles of a triangle are supplementary,that is 180°

so the equation is

x+x+2x=180°

4x=180

x=180/4

x=45

therefore the angles are

x=45°

x=45°

2x=2×45=90°
