Question

Using the figure, answer the following questions

(i) What is the measure of angle x°?
(ii) What is the measure of angle y°?

Answer 1

From the figure x° and 125° are vertically opposite angles.

So they are equal

ie x° = 125°

Also y° and 125° are linear pair of angles.

∴ y° + 125° = 180°

y° + 125° – 125° = 180° − 125°

y° = 55°

x° = 125°,

y° = 55°
