Its a parallelogram (a)Find the value of x
(b)the length of KM
(c)the measure of angle HMK

see below

Step-by-step explanation:

a) set the two equations equal to each other and isolate the variable

3x+8 = 7x-24

3x+32=7x

32=4x

x=8

b) Plug in the value of x we got into the equation

7(8)-24 = 56

56-24=32

c) Angle k and h are both 72 (add 20 and 502 together) so h+k=144

J and m are going to have the same measurement so we can set up and equation, we also know all angles must add up to 360

144+2x=360

2x=216

x=108

HMK=108

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
