Question

One angle of triangle is 65 degree. Find the remaining two angles if their difference is 20 degree.

Answer 1

Answer:

let the 2 angles be

x and x+20

as we know;;

65+x+x+20=180

85+2x=180

2x=180-85

2x=95

x=47.5

therefore the two angles are

47.5

and

67.5

Answer 2

Answer:

x+(x+20)+65=180

2x+85=180

2x=95

x=95/2

or two angles will be 45 and 65
