In the drawing, A, C, and D are collinear and AB is tangent to the circle B. Using the values shown, what

is the measure of CD?

2? if not the correct answer you might need to provide more information

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
