Question

one angle of a triangle is one third of the other and third angle is 19 degrees more than the greater of the two angle find the three angle of triangle​

Answer 1

Step-by-step explanation:

Let angle A be x.

A.T.Q

angle B=1/3x

angle C=x+19

Acc. to angle sum property of triangle

A+B+C=180°

x+1/3x+(x+19)=180°

2x+1/3x+19=180°

7/3x=180-19

7/3x=161

x=161*3/7

x=69°

x=Angle A=69°

1/3x=angle B=23°

x+19=angle C=88°
