Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
sin(∠ADB) =
= 0.74231
m∠ADB =
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
the point, M, that divides segment AB into a ratio of 3:1
A is at (-4, -2) and B is at (4, -10).
Apply section formula
Here m,n is the ratio
m =3, n= 1
A is (-4,-2) that is (x1,y1)
B is at (4, -10) that is (x2,y2)
plug in all the values in the formula
(2, -8)
Point M is (2,-9)
