How do u even do this? plz show me how

a)

she drew a Δy = 6 with a slope of 11°, well, based on that angle/ratio table above, 11° corresponds to a line with a slope ratio of 1/5, meaning

b)

she drew a Δx = 40 on a line with slope of 72°, therefore

c)

Δx = 23 and Δy = 23, therfore then

each side has a different length.  

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
