O so, i know that the circle is NOT a function because it doesnt pass the vertical line test. *To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Looking at the graph we can determain the domain is indeed greater or equal to negative 4 and less than or equal to 4.

x2+y2=16 is correct (4*4=16), and the last one... doesnt really make sense to me. So im guessing thats wrong.

ian gonna lie that is way to much

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
