Question

in triangle PQR Q=50 R=120

Answer 1

in triangle PQR Q = 50 , R = 120
then angle P = ?
we know that sum of angle of a triangle is 180
then P + 50 + 120 = 180
then P = 180 –170 = 10

Answer 2

We have given that
Q=50 and R=120
We know that sum of three side of triangle is 180
Then
P+Q+R=180
P+50+120=180
P+170=180
P=180-170
P=10
