When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23

Now solve for B.
6(23) + 19 = B
138 + 19 = B
157 = B

The measure of angle B is 157 degrees

Hope this helps =)

Find the points of Intersection of these graphs
geniusboy [140]

Answer:

the line crosses the parabola at (-2,4) and (3,9)

Step-by-step explanation:

y=x^2

y=x+6

set them equal to each other

x^2=x+6, now set it equal to zero

x^2-x-6=0, now find the root

(x+2)(x-3)=0, the x=-2, and x=3; now substitute into any of the equation to find the points where graphs intercept

at x= -2, y=(-2)^2=4, so one point is (-2,4)

at x=3, y=(3)^2=9, so other point is (3,9)

the line crosses the parabola at (-2,4) and (3,9)

IrinaK [193]
I have a great list that might help you learn some octagon facts!

1. Umbrellas are in the shape of an octagon.
2. As a symbol, octagons symbolize regeneration, infinity, rebirth, and transitions.
3. Octagons are hard to draw...You can find Octagons anywhere if you just look... just kidding only around stop signs. Lol
4. Octagons have eight angles and eight sides.
5. Did you know that you can draw an octagon with just a compass and ruler.

There ya go!
Happy to help. Let me know if you have more questions or any concerns.
