Question

In each of the figure given below find the value of x and y​

Answer 1

Answer:

(i) x = 70° and y = 40°

(ii) x =60° and y = 80°

Step by step explanation:

(i) x + 110° = 180° ( linear pair)

=> x = 180°-110°= 70°

x + y = 110° ( Exterior angle of triangle is = the sum of opposite interior angles)

=> 70°+y =110°

=>y = 110°-70° = 40°

(ii) x + 90° +30°=180° ( Angle sum property of triangles)

=>x = 180°-(90+30)°

=>x = 120°

To find out y here, look at the attachment given.
