Question

one angle of a triangle is twice the
second angle.the third angle is equal to the sum of both angles find their degree measures.​

Answer 1

Answer:

72 degree is the answer from my opinion

Answer 2

Answer:

let the first angle be 2x

so, second angle will be x

third angle = 2x+x = 3x

we know that sum of angles of a triangle is always 180°

therefore      x+ 2x + 3x = 180

                           6x        = 180

                             x         = 180/6

                             x         = 30

first angle = 2x = 60°

second angle = x= 30°

third angle = 3x = 90°

hence the angles are 60°, 30° and 90°
