Question

Measures of two angles of a triangle are equal and third angle is twice the measure of one of the equal angles. find the measures of the angles of the triangle.

Answer 1

Answer:

90 , 45 and 45

Step-by-step explanation:

Let the first two angles be x

Therefore 3rd angle = 2x

2x + x + x = 180 degrees ( angle sum property of triangles )

4x = 180 degrees

x = 180/4

x = 45 degrees

2x = 2 * 45= 90 degrees

So first angle = 45 degrees, second angle = 45 degrees, third angle= 90 degrees.
