Step-by-step explanation:
Equation: 3.9^2 + x^2 = 11^2
x = 10.29
Well, assuming that Liam, Raj, and Gemma all have squares identical to each other, then you would first add them all up. 14+12+15=41. Then, you would divide the total number of squares by the number of squares in a quilt. 41/10=4.1, or 4 1/10.

Using the catchphrase SohCahToa, we can determine that the cosine ratio is equal to the length of the side adjacent to the angle over the length of the hypotenuse of the right triangle.
To find the cos∠A, we will look for side lengths BC and AB.
cosA =
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
Since
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
is already in it's simplest form, we can conclude that the cosine of ∠A is
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
.

When you multiply powers, (add) the exponents.
When you divide powers, (subtract) the exponents.
When you raise a power to a power, (multiply) the exponents.
Anything to the zero power equals (1).
When you have a negative exponent, (flip it) and make it (positive).
