Question

lf the three angles at a point are in the ratio 1:4:7, find the value of each angles​

Answer 1

Answer:

let us take x as a each angle.

1x+4x+7x=180°(angle sum property)

12x=180

x=180÷12

x=15

hence given angles:

1x=15°

4x=4×15=66°

7x=7×15= 105°

therefore the value of each angles are 15°,66°and 105° respectively.
