Plsss help!!!<br>y = ??<br>X =???​
Lyrx [107]

Answer:

x=80* y=20* and X=100*

Step-by-step explanation:

If we assume PQ || OR then by alternate interior angles x is equal to 80 degrees and y is equal to 20 degrees.

We know that a triangle adds up to 180 degrees.

Angle ROX and XRO add up to 100 degrees. Leaving RXO equal to 80 degrees. (180-100=80).

By opposite angles, QXP is equal to 80 degrees also.

Then we are left with solving for X.

Supplementary angles add up to 180 degrees.

Subtract angle OXR from 180 and we are left with angle OXP = X = 100 degrees.

7.(1,0) and (-4,0)

8.  (-3,0) and (-2,0)

Step-by-step explanation:

7.

When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are 1 and -4

(1,0) and (-4,0)

8.  When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are -3 and -2
