Question

The angle of a triangle are in the ratio 2:3:4. Find the angle

Answer 1

Answer:

sum of the three angles of a triangle is 180°

the angles are in the ratio 2:3:4

so the 1st angle is 2×180/(2+3+4)°

=2×180/9

=2×20°=40°

the 2nd angle is 3×180/(2+3+4)°

=3×180/9°

=3×20°=60°

the 3rd angle is 4×180/(2+3+4)°

=4×180/9°

=4×20°=80°
