Question

Mention the kind of triangle also.
7. The angle of a triangle is in the ratio of 2: 3: 4. Find the measure of each angle of the triangle.
loo of an isosceles triangle measures 55°. Determine the other angles.​

Answer 1

Answer:

The angle of a triangle is in the ratio of 2: 3: 4. Find the measure of each angle of the triangle.

Let the 3 angles of the triangle be 2x 3x and 4x.

sum of measures of a triangle = 180°

Therefore 2X +3x+4X= 180°

9X = 180°

X=180°/9

X = 20°

Angle 1 = 2X= 2×20°= 40°

Angle 2= 3X= 3×20° = 60°

Angle 3 = 44X= 4× 20° = 4x20° =80°
