Question

In ∆ PQR, if ∠P = 32 and ∠Q = 68 then the longest side of triangle PQR is

Answer 1

Answer:

<P +<Q+<R=180°

32°+68°+<R=180°

100°+<R=180°

<R =180°-100°

<R =80°

Answer 2

Step-by-step explanation:

angle r = 180⁰-(32+68)

= 180⁰-100⁰

=80⁰

angle r is the biggest angle

so,PQ side is the longest because side opposite to the biggest angle is the longest side.
