Find the measure of arc ABD.

Question

A.180

B.330

C.275

D.347

Answer 1

A to B is marked as 60.

B to C would be 180, half the circle.

C to D is a right angle, so it is 90.

The total is 60+180+90 = 330° or B

Answer 2

B. 330

However, David, if you provide details why did you stuck on this problem, you can benefit much more.

For example,

1) You didn't know that the number of degrees of a full circle is 360;

2) You knew it is 360 but didn't know why, so you cannot even remember this because it make no sense;

3) You know well all above, but failed on arithmetic;

4) You didn't know what ARC means;

5) You didn't know what "measure of arc" means;

6) You didn't know what does that pink part of rectangle is;

7) All above.

Those are all questions you have to ask yourself. Otherwise you will ask the same questions over and over again.
