The Pythagorean Theorem states that a triangle's hypotenuse is equal to the square's of the other two sides of the triangle.
a² + b² = c<span>²
a = side of triangle
b = other side of triangle
c = hypotenuse (squared)
Find the square root to find the accurate length of the hypotenuse.</span>
Answer:
Step-by-step explanation:
![Tan \ B =\frac{4}{3} = \frac{opposite \ side \ of B}{adjacent \ side \ of B}](https://tex.z-dn.net/?f=Tan%20%5C%20B%20%3D%5Cfrac%7B4%7D%7B3%7D%20%3D%20%5Cfrac%7Bopposite%20%5C%20side%20%5C%20of%20B%7D%7Badjacent%20%5C%20side%20%5C%20of%20B%7D)
BC = 15 cm
3x = 15
x = 15/3 = 5
AB =4x = 4*5 = 20 cm
Pythagorean theorem,
AC² = AB² + BC²
= 20² + 15 ²
= 400 + 225
= 625
AC = √625 = 25 cm
AC = 25 cm
![Sin \ A = \frac{opposite \ side \ of \ angle A }{hypotenuse}\\\\ = \frac{BC}{AB}=\frac{15}{25}=\frac{3}{5}](https://tex.z-dn.net/?f=Sin%20%5C%20A%20%3D%20%5Cfrac%7Bopposite%20%20%5C%20side%20%5C%20of%20%5C%20angle%20A%20%7D%7Bhypotenuse%7D%5C%5C%5C%5C%20%20%3D%20%5Cfrac%7BBC%7D%7BAB%7D%3D%5Cfrac%7B15%7D%7B25%7D%3D%5Cfrac%7B3%7D%7B5%7D)
