Question

The second angle of a triangle is twice as large as the first. The measure of the third angle is 20
degrees greater than the first. How large are the anges?​

Answer 1

let first angle be X

according to questions

X + 2x+ (X+20)=180

3x =160

X = 160/3

largest angle is

second angle = 320/3

Answer 2

Given ; The second angle of a triangle is twice as large as the first. The measure of the third angle is 20

degrees greater than the first

To Find ; Large are angels

Solution ; Let the first angle is x

Then according to question

Second angle of triangle = 2x

Third angle of triangle = x+20

Angel sum of a triangle is 360 that is the sum if all the angles of a triangle together make a sum of 360

In triangle sum of all angles in 360

x+2x+x+20=360

4x=340

x=85

Second angle = 170

Third angle = 105

Hence the three angles are 85, 170 and 105
