Q2 explanation : let the name of triangle be ABC

vertex angle (c) = 30

we know that A = B ( opposite angles of equal sides are equal )

so,let the A and B be x

A+B+C = 180°

x + x + 30= 180°

2x + 30° = 180°

2x = 180°-30°

2x = 150°

x = 150/2

x = 75°

A = B = 75°

so, vertex angle is 75°

Q3 Explanation: By Pythagoras theoram

QR^2 = PR^2+QR^2

OR = 14^2+50^2

OR = 196+2500

QR^2 = 2696

QR = root 2696

sorry, I try to do 3 que but I cant
