# Something I learned this week (Oct. 24-28)

This week, I learned how to use the acronym SOH CAH TOA to help find angles and sides of right angled triangles.
SOH represents “sine, opposite, hypotenuse” So to find the sine, you put the ratio of the opposite side over the hypotenuse. In this example, in respect to angle C, the sine is $\frac{24}{25}$
CAH represents “cosine, adjacent, hypotenuse”  To find the cosine, you put the ratio of the adjacent side over the hypotenuse. In this example, in respect to angle C, the cosine is $\frac{7}{25}$
TOA represents “tangent, opposite, adjacent” To find the tangent, you put the ratio of the opposite side over the adjacent. In this example, in respect to angle C, the tangent is $\frac{7}{24}$
