Question

if x, y and z are three angles laying on a straight line a) if y=x+z find the value of y b) x=y=z find the value of z​

Answer 1

Answer:

125°

Step-by-step explanation:

x=55°

[Vertically opposite angles]

Now 55

+y=180° [Linear pair]

⇒y=180°

−55°

o

=125°

Also y=z=125° [Vertically opposite angles]

Thus, x=55°

,y=125°

and z=125°
