Question

In ∆, ∠ : ∠: ∠ = 5 : 7 : 8. Find the measure of each angle of ∆ .
​

Answer 1

Answer:

let the angle be x =5 x 7 x 8 x

sum of angle Angle = 360

5x+7x+8x=360

20x=360

x=360/20

x=18

so.....

the angles are...

5*18=90

7*18=126

8*18=144

Answer 2

Answer:

1 angel= 45

2angel = 63

3 angel =72

Step-by-step explanation:

let x

5x+7x+8x = 180

three angel sum is 180

20x =180

x =180/20

x= 9

so

5x= 5×9= 45

7x= 7×9= 63

8x = 8×9= 72
