Question

If l/m find the value of x and the value of y.

Answer 1

Answer: the answer isn’t C

Explanation:

I just did the test. I believe the answer is D

Answer 2

The measure of x and y are 45° and 45° respectively.

Explanation:

From the figure, it can be seen that the line l is parallel to line m, and x is the angle made between the horizontal axis and the vertical axis, therefore the measure of the angle x will be 90°.

Using the straight line property, we get

`x^(\circ)+y^(\circ)+45^(\circ)=180^(\circ)`

Substituting the value of x in the above equation , we get

`90^(\circ)+y+45^(\circ)=180^(\circ)`

`y+135^(\circ)=180^(\circ)`

`y=45^(\circ)`

Therefore, the measure of x and y are 45° and 45° respectively.
