Step-by-step explanation:
I had just taken the quiz
In triangle ABD,
= 30°
Applying trigonometry,

Now, In triangle ABC,
= 60°
Applying trigonometry,

Measure of CD = BD - BC
_____________________________

For M and N to be parallel, the lower given degree on line M must be equal to the lower equation on line M.
3x +5 = 65
Subtract 5 from each side:
3x=60
Divide both sides by 3:
x = 60 / 3
x = 20
