Question

The measures of the angles of KLM are in the ratio 2:3:4. What are the measures of the angles? 40°,

Answer 1

Step-by-step explanation:

let the angle of the triangle be 2a,3a,4a, respectively

recall that sum of the angle in a triangle is 180°

= 2a+3a+4a = 180°

= 9a = 180°

a = 180/ 9 = 20°

= smallest angle = 2a= 2× 20° = 40°
