Question

Plz answer fast correctly
It is important
Plz mention the property used also .

Answer 1

Answer:

Step-by-step explanation:

1) Its an isosceles triangle, Therefore by using isosceles triangle property

x+x+50 = 180degree (Angle sum property)

2x+50 = 180

2x = 180-50 = 130degree

x = 130/2 = 65degree

2)Its a right triangle, Therefore by using pythagoras theorem

PR^2 = PQ^2+QR^2

         = 8^2+6^2 = 64+36 = 100

therefore PR = 10cm

3) By using exterior angle property

x = 60 + 70

x  = 130 degree

Answer 2

Here is your answer..hope it helps
