What is the measurement of angle POR
IgorLugansk [536]

Let us observe the given figure,

When two lines intersect each other, the angles opposite to each other are Vertically Opposite Angles. Vertically opposite angles are always equal in measure.

As, we can observe that the given lines intersect each other, and they form vertically opposite angles as \angle POR , \angle SOQ and  \angle POS , \angle ROQ

Therefore, \angle POR = \angle SOQ

Substituting the given measures of the angles, we get

91-x^\circ = x+ 7^\circ

91-7 = x + x

84 = 2x

x = \frac{84}{2}

So, x = 42^\circ

Since, the measure of angle POR = (91-x)^\circ

= (91-42)^\circ

= 49^\circ

Therefore, the measure of angle POR is 49 degrees.

Which table values can be defined by the function y=2x+3
lbvjy [14]

Answer:

beggining poit:3   second point (potentially):  1,5

Step-by-step explanation:

in the y intercept 3 is it so which ever has a 3 as the starting point there could be an option

for the 2x part that is the slope otherwise known as rise over run so what you do is that you turn it to a fraction over or under 1 meaning you rise for 2 and go to the right 1

rise 2

      _

run  1

in order to rise 2 you go up 2 from the y intercept(3) and in order to run you go right since its a positive

once you plot those two dots then you draw a line across
