Question

the angles of a triangle is 3x,(2x+20),(5x-40).Find the angles​

Answer 1

Answer:

we know that,sum of all angles of an ∆ is 360°

according to angle sum property,

3x+2x+20+5x-40=180

10x-20=180

10x=200

x=20°

so,

first angle=3(20)=60°

second angle=2(20)+20=40+20=60°

third angle=5(20)-40=100-40=60°

hope it helps you....✌✌
