What is tan A for this triangle

D (last one)

Step-by-step explanation:

In order to find tangent for <A, it's opposite/adjacent. In this case, it is 80/39. 80 is the opposite side and 39 is the adjacent side to <A. The answer is the last one, D.

Your answer is D, or 80/39.

This is because tangent refers to the relationship between the opposite and adjacent sides of the given angle.

Since A is our given angle, we can identify the opposite side, which is 80, and the adjacent side, which is 39, and then fill in the relationship.

Hopefully this helps! :)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
