Angles x and y are supplementary. angle x is 3 times the measure of angle y. what is the measure of angle x?
45°
60°
120°
135°

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
