Answer:

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

Step-by-step explanation:

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

Answer:

Step-by-step explanation:

m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°

From ΔABC:

m∠ABC + m∠BCA + m∠BAC = 180°

65° + 35° + m∠BAC = 180°

m∠BAC = 180° - 100°

m∠BAC = 80°
