Question

Of the 3 angles of the triangle one is twice the smallest and another one is thrice the smallest. Find the angles.

Answer 1

let the smallest angle be= x

then second angle will be= 2x

and the third angle will be= 3x

we know sum of angles of a triangle is 180°

so,btp,

x+2x+3x=180°

=>6x=180°

=>x=30°

so,first angle is =30°

second angle is =(2×30)°=60°

third angle is =(3×30)°=90°

SO,three angles of the triangle are 30°,60°and90°
