Answer:
measure of one of the angle of a triangle be =x
measure of second angle is twice of first=2x
measure of third angle is thrice of first =3x
x+2x+3x=180° [sum of angles of a triangle]
6x=180°
x. =30°
NOW,
2x=(2×30)=60°
3x=(3×30)=90°
Step-by-step explanation:
quadrilateral is a triangle because sum of all angle of a triangle is 180°
