Determine mABDarc using the appropriate theorems and postulates.
!no absurd answers please, thank you!

=================================================

Work Shown:

Given Info

arc BCD = 21

arc EF = 35 (this is the shortest distance along the circle from points E to F)

--------------

Using arc EF, we can say that angle ECF is also the same measure. The central angle and the arc measure are always equal.

angle ECF = 35

Then using the vertical angle theorem, we can say that

angle ACB = angle ECF

angle ACB = 35

From the fact that central angle ACB is 35 degrees, we can then say minor arc AB is also 35 degrees

Through similar reasoning, minor arc BD = angle BCD = 21

--------------

So we have

which add to

(minor arc AB)+(minor arc BD) = arc ABD

(21)+(35) = arc ABD

56 = arc ABD

arc ABD = 56

See the diagram below and hopefully it will clear up any confusion. The diagram is composed of two figures. Figure 1 shows how to get minor arc AB. Figure 2 shows how to get minor arc BD.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

1/4 because there is 4 grades.
