In δabc, which trigonometric ratio has the value a/c

a. tan a
b. cos a
c. tan c
d. cos c
e. sin c

Step-by-step explanation:

From the diagram, side length is opposite to angle A and side length is adjacent  to angle A.

Recall the mnemonics SOH CAH TOA.

We use TOA, because it involves opposite and adjacent.

The correct choice is A.

The answer is:  A. Tan(A)

Since it's a right triangle, we must remember the following trigonometric identities:

We are going to work with the tangent indentity, so:

If we are looking which a trigonometric ratio/relation which is equal to:

Also, from the image we can see that:

So, using the tangent identity, which is equal to:

So, the correct option is A. Tan(A)

Have a nice day!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
