Question

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

Answer 1

Step-by-step explanation:

so far I know.... at a point means 360°... so,

let the common multiple be x

angle1=1×

angle2= 4x

angle3=7x

1x+4×+7×=360°

12×=360

×=360/12

×=30

therefore,

<1=30°

<2=4×=30×4=120°

<3=7×=30×7=210°
