Step-by-step explanation:
Do you know SOHCAHTOA
Sin = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
#1
We have to find cos(x) = adjacent/hypotenuse
![cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}](https://tex.z-dn.net/?f=cos%28x%29%20%3D%20adj%2Fhyp%5C%5C%3D%5Cfrac%7B24%7D%7B26%7D%20%3D%20%5Cfrac%7B12%7D%7B13%7D)
#2:
We are given an angle of 30 degrees and an opposite side of 15
We need to find the adjacent side, so we can use Tangent
![tan(30) = \frac{15}{adj}](https://tex.z-dn.net/?f=tan%2830%29%20%3D%20%5Cfrac%7B15%7D%7Badj%7D)
![adj = \frac{15}{tan(30)} = 25.98 = 26](https://tex.z-dn.net/?f=adj%20%3D%20%5Cfrac%7B15%7D%7Btan%2830%29%7D%20%3D%20%2025.98%20%3D%2026)
#3
We are given an angle and an opposite side and we have to solve for hypotenuse.
We can use sin
![sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5](https://tex.z-dn.net/?f=sin%2843%29%20%3D%20%5Cfrac%7B16%7D%7Bx%7D%20%5C%5Cx%20%3D%20%5Cfrac%7B16%7D%7Bsin%2843%29%7D%20%3D%2023.46%20%3D%2023.5)
#4:
We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent (
, but not 1/tan(x))
![tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759](https://tex.z-dn.net/?f=tan%28x%29%20%3D%20%5Cfrac%7B36%7D%7B19%7D%20%5C%5Carctan%2836%2F19%29%20%3D%20x%5C%5Cx%20%3D%2062.1759)
#5
We are given an opposite side and the hypotenuse, we can use sin
![sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43](https://tex.z-dn.net/?f=sin%28x%29%20%3D%20%5Cfrac%7B19%7D%7B28%7D%5C%5Cx%20%3D%20arcsin%2819%2F28%29%20%3D%2042.73%20%3D%2043)
