Question

the three angles of a triangle are the ratio 1:2:1.find all the angles of a triangle . classify the triangle in two different ways .

Answer 1

Let the 1st angle of the triangle be 1x
Let the 2nd angle of the triangle be 2x
Let the 3rd angle of the triangle be 1x
Sum of all the angles of a triangle = 180°

Angle 1 + Angle 2 + Angle 3 = 180°
1x + 2x + 1x = 180°
4x = 180°
x = 180/4
x = 45

1x = 1×45 = 45°
2x = 2×45 = 90°
1x = 1×45 = 45°


HOPE IT WILL HELP U ✌️✌️
