Question

in trangle PQR if angle P=50 R=45 find angle Q

Answer 1

sum of all angle of triangle is 180

given

50+ 45+Q=180

95+Q=180

Q=180-95

Q=85

Answer 2

In triangle PQR,

Given, angle P=50

angle R=45

We know that the sum of all the three angles of a triangle is 180 degree.

So angle P + angle R + angle Q=180

That is,50+45+Q=180

95+Q=180

Q=180-95

=85

Hope it helps!
