Answer:

a) 39 degrees

Step-by-step explanation:

angle REB + angle JEB = 180 degrees (because J, E, and R are collinear)

=> angle REB = 180 - angle JEB = 180 - 132 = 48 degrees

angle REB + angle ERB + angle RBE = 180 degrees (because the sum of 3 angles inside a triangle is 180 degrees)

=> angle RBE = 180 - angle REB - angle ERB = 180 - 48 - 93 = 39 degrees

Which proportion can be used to show that the slope of JL is equal to the slope of MP

Ilya [14]

Answer:

See below and attached

Step-by-step explanation:

As per the graph we have:

Coordinates of JL are J(-7, 4), L(-4, 0)

Coordinates of MP are M(-10, 8), P(-1, -4)

Slope formula is:

m = (y₂ - y₁)/(x₂ - x₁)

Slope of JL:

(0 - 4)/(-4-(-7)) = - 4 / 3

Slope of MP:

(-4 -8)/(-1- (-10)) = -12 / 9 = - 4/3

T is the midpoint of rq if r=12 t=-3 what is q

Gemiola [76]

Well how far away is t (-3) from r (12)?
It's 15 away. It gets 15 less, so q will be 15 more.
12+15=27
q is 27
