Question

one angle of the triangle is 75° and other two angles are in the ratio 1:2. find the unknown angles of the triangle.

Answer 1

we know that the sum of all the angles is 180 and one angle is given= 75°
so, 180°-75°= 105°
the sum of other two Angel is 105°
but they are in ratio 1:2
If we take one as X so another will be 2X.
X+2X=105°
3X=105°
X=105°/3
X=35°
One angle is =35°
another angle is = 70°

Hope it will help you

Answer 2

first angle is .... 35 degree

2nd angle is 70degree
