Question

In triangle PQR Angel P=80 and angleQ=60 and angle R=40 find the biggest side and the smallest side of triangle PQR

Answer 1

A=50

B=60

A+B+C=180

50+60+C =180

110+C =180

C =180-110

C=70

angle opposite to longest is longest side i.e

side opposite to <C is AB is biggest

shortest side is opposite to <A is BC is shortest

Answer 2

QR is the biggest side and PQ is the smallest side of triangle PQR.
