Step-by-step explanation:

because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66

angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA

angle ADC = 180 -50 -66 = 64

Answer:

slope = $\frac{3}{4}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (5, 3 ) and (x₂, y₂ ) = (9, 6 )

m = $\frac{6-3}{9-5}$ = $\frac{3}{4}$
