Question

in the fig x=36, the value of y is:​

Answer 1

y=

4y + x = 180

4y + 36 = 180

4y = 180- 36

4y = 144

y = 144/4 = 36°

opt (a) 36°

Follow!!

Answer 2

Answer:

x = 36 °

3x = 3× 36 ° = 108°

x + 3x + 2y + 4y = 360° (s. of all angles in a quadrilateral)

36° + 108° + 6y = 360°

6y = 360° - 144° = 216°

y = 216/6 = 36°

therefore, y = 36°
