Question

In triangle pqr, angle p=70 degree and angle r=30 degree?? Which side of this is triangle is the longest?Give reason for your answer.

Answer 1

angle q=180°-(70+30)
→180-100
→80°

The side opposite to angle q i.e. PR is the longest because the side opposite to largest angle is longest.

Answer 2

Answer:

Step-by-step explanation:

angle P = 70°

angle R =30°

then,

angle Q = 180°-(70+30)°

= 80°

as you can see that the largest angle is angle Q so, the largest angle must be opposite to it.

So, PR is the longest side.
