Question

what is the answer??????​

Answer 1

Q1) PROPERTY used is sum of all angles of a triangle is 180 degrees.

a) x = 180-110 = 70 degree

b) x = 180-120= 60 degree

c) x = 180-140= 40 degree

d) 2x = 180-50 = 130 so, x = 130/2 = 65 degree

e) x = 60 degree because all angles are same so its an equilateral triangle too.

f) 3x = 180-90= 90 so, x = 90/3 = 30 degree

Q2)

a) 180-120 = y = 60 degree

and 60+ x = 120

so, x = 60 degree

b) y = 80 degree

and x = 180 - 130 = 50 degree

c) 180 - 110 = y

so, y = 70 degree

and x + y = 180

so, x = 180 - 70 = 110 degree

hope this helps you
