[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is one leg
b is another leg
c is hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

a = 19

b = x

c = 21

Step 2: Solve for x

Substitute [PT]: 19² + x² = 21²
Isolate x term: x² = 21² - 19²
Exponents: x² = 441 - 361
Subtract: x² = 80
Isolate x: x = √80
Simplify: x = 4√5

If f(x) = x and g(x) = 2x + 7, what is f[90X)] when g(x) = 11?

kumpel [21]

$\bf \begin{cases} f(x) = x\\ g(x) = 2x+7 \end{cases}~\hspace{7em}g(x)=11\implies \stackrel{g(x)}{11}=2x+7 \\\\\\ 4=2x\implies \cfrac{4}{2}=x\implies \implies \boxed{2=x} \\\\[-0.35em] ~\dotfill\\\\ f[90x]\implies f\left[90\left( \boxed{2} \right)\right]\implies f(180)=\stackrel{x}{180}$
