Explanation:

In the given figure the "hidden" vertex of the larger triangle is A.

Since, angle D is a right angle, both triangles BDC and CDE are right triangles (and they are also similar).

Since angle B and angle C have the same measure and angle D measures 90° (right angle), angle A and angle C are complementary, i.e.

For complementary angles, the sine of one acute angle equals the cosine of the other acute angle.

So, the sine of angle C is equal to the cosine of angle  B, i.e. cos (B) = sin (A).

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
