Question

Find the value of x, y and z
​

Answer 1

y = 125°

z = 125°

Explanation:

x = opposite angle = 55°

y+z = 360 - 55 - 55 = 250°

y+z = 250°

y = z (opposite angle)

y = z = 250° : 2 = 125

Answer 2

Explanation:

Here the value of x will be 55° as it is vertically opposite to 55°....

Now ,

y + 55° = 180° ( straight angle )

y = 180° - 55°

y = 125°

Now ,

z = y ( vertically opposite angle )

z = 125°

`...`

hence...the value of x is 55° and y and z is 125°
