Question

In ∆PQR angle P=2 angle Q and 2 angle R =3 angle Q , Calculate the angle of ∆PQR

Answer 1

angle p=2 angle Q
angle r=3 angle Q
angle Q=angle Q
we know that sum of all angles in a triangle is 180 degrees
so, angle P+angleQ+angleR=180degrees
2Q+3Q+Q=180
6Q=180
Q=180/6
Q=30
so,angleP=2angleQ=2*30=60degrees
angleR =3angleQ=3*30=90degrees
angle Q=30degrees

Answer 2

Answer:

p=30degrees

Q=60degrees

R=90degrees
