Question

Angles of a triangle are in ratio 1:2:4.find the angles?

Answer 1

Step-by-step explanation:

Given ratio of angles of a triangle =1:2:4

They be x,2x,4x

The sum of all the three angles of a triangle =180°

=>x+2x+4x=180°

=>7x=180°

x=180°/7=25.71°(approximately)

the angles are: x=25.71°

2x=2×25.71°=51.42°

4x=4×25.71°=102.84°

the angles are 25.71°,51.42°,102.84°(approximately)
