in the triangle the first Angele is 15⁰ more than the second Angele the third Angele is twice the first Angele find the measure of the each angele of the triangle​

Answer:

1st angle be ‘x’

2nd angle is : x+12

3rd angle is : 2x

As we know sum of angles in a triangle is 180

-> x+x+12+2x = 180

4x + 12 = 180

4x = 168

X = 42

Second angle : x + 12 -> 42+12 = 54
