Question

two angle of a triangle are equal and its third sides is double of the equal angle find the measure of three angle of triangle ​

Answer 1

Answer:

Let one of the angle be x

The other two angles are x and 2x

.

STEP 1: Solve x:

Sum of the angles = 180°

x + x + 2x = 180

Combine like terms:

4x = 180

Divide both sides by 4:

x = 45

.............................................................................................

STEP 2: Find the angles

1st angle = x = 45°

2nd angle = x = 45°

3rd angle = 2x = 2(45) = 90°

.............................................................................................

Answer: The angles are 45°, 45° and 90°

Answer 2

Let the equal sides be x,

3rd side= 2x

x+x+2x= 180°

4x= 180°

x= 45°

Equal angles = x= 45°

3rd side= 2x = 2*45= 90°

Hence the angles are 45°,45° and 90°
