Question

1. In three angles of a triangle, one is double the smallest and another is thrice times the
smaller. Find the angles.​

Answer 1

Answer:

1st angle = X

2nd angle = double the smallest = 2*X = 2X

3rd angle = thrice times the smaller = 3*X =3X

we know that, sum of three angles of a triangle = 180.

so, X+2X+3X =180

6X= 180

X= 180/6

X= 30.

so, 1st angle =X = 30.

2nd angle = 2X = 2*30 = 60.

3rd angle = 3X = 3*30 = 90
