Complete the statements. x² + y²=y
is written in polar form as. r = 3sin A is written in rectangular form as x^2+y^2 =

x^2+y^2=y is the same as r=sin(theta). r=3sin is the same as x^2+y^2=3y

Step-by-step explanation:

9987

step-by-step explanation:

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.
