Question

012. If the angles of a triangle ABC are in the ratio 2:3:4, find the measure of the anges A,
B and C​

Answer 1

Step-by-step explanation:

From given ratio A:B:C=2:3:4

so let A=2k, B=3k and C=4k

since it is triangle we know that sum of all the angles in a triangle is 180 from angle sum property

so, 2k+3k+4k=180

9k=180

k=180/9

k=20

therefore,

A=2k=2×20=40

B=3k=3×20=60

C=4k=4×20=80
