Question

In each of the following figures, find the value of x:
​​

Answer 1

Answer:

Since, triangle ACD is an isosceles triangle

angle A = angle D

Therefore, angle A = 30°

angle C = 120°

in triangle ACB, angle C = 60°

Therefore, x = 55° ... Ans

Answer 2

Step-by-step explanation:

triangle ACD is isoceles so angle CAD = CDA = 30

so angle BAD = 65+30=95

hence x = 180(sum of the interior angles of triangle)- (95+30)= 180-125=55

therefore x= 55
