i suppose you can set B as (0, 0), put the whole thing on a coordinate plane, and solve it that way by setting DC's length as x.

HOPE THIS *hint* HELPED!

the multiplication and division is pretty much 0, the its just 67896986898976897698678969568446568.

LOLOLOLOLOLOL

i had it at the start, but i dont have it now, i think if you register long enough, it will go away after like 3-4 days

it reaches its full rotation after the wavelength number of seconds, or 35-15 or 20 seconds, so the answer is 10/20 * 360 degrees or 180 degrees.

HOPE THIS HELPED!

pls be more descriptive when the say the centroid is...?

the equation of the solid line is y = -x+4 shaded bit is under that so it is y <= -x+4

the equation of the dashed line is y = (1/3)x shaded bit is above that so it is y > (1/3)x because it is dashed

so the answer is y <= -x+4 and y > (1/3)x

HOPE THIS HELPED!

HOPE THIS HELPED!

it is V and W, only they follow vertical line test.

HOPE THIS HELPED!

whaaaaa... lol

it is A or D because of two equal sides, and the last angle is 70 degrees so it is A.

HOPE THIS HELPED!
