Answer 2

2) sum of all angles of triangle is 180

let the missing angle be x

72+58+x = 180

x= 180-(72+58 )

x= 180-130

x= 50

the measure of the third ang is 50.

3) let the angles are x, 3x ,5x

sum of all angles of triangle is 180

x+3x+5x = 180

9x = 180

x= 180/9 = 20

hence angles are 20, 60, 100.

4) let the missing angle be x

sum of all angles of triangle is 180

90+50+x = 180

x= 180-140

x= 40

hence the missing angle is 40

5) let the same angles are x .

sum of all angles of triangle is 180

x+x+ 110 = 180

2x = 180-110

2x= 70

x= 35

hence the angles are 35
