Each page in a coin collection album has 4 rows of coins with 3 coins in each row, if the album contains 72 coins, how many pages are filled with coins?

y = 6.693

Step-by-step explanation:

You must be doing trig. There is no other way your could solve this problem. So you are working with one of the 6 fundamental definitions in trigonometry.

One of the 6 = opposite (y) / hypotenuse.

If you look this up in your notes, you will find out that the definition is

sin(angle) = opposite / hypotenuse.

Givens

Sin(26.5)

hypotenuse= 15

Solution

You want y which is the opposite side.

Sin(26.5) = y / 15

Sin(26.5) = 0.4462

0.4462 = y / 15                 Multiply both sides by 15

0.4462 * 15= y /15 * 15     Combine

y = 6.693
