Use the triangle shown to find the ratios.

COS(A)= ?

tan(C) = ?

Step-by-step explanation:

cos A=10/26=5/13

tan C=10/24=5/12

Step-by-step explanation:

The right triangle trigonometric ratios are:

We are asked to find the cosine of A. Therefore, we need the adjacent and hypotenuse.

Substitute the values into the ratio.

Reduce the fraction. Both the numerator and denominator can be divided by 2.

We are also asked to find the tangent of C. We need the opposite and adjacent.

Substitute the values into the ratio.

Reduce the fraction. The numerator and denominator can be divided by 2.

The cosine of A is 5/13 and the tangent of C is 5/12

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
