Question

How do you find the base in the Pythagorean theorem, c=18, a=9, what is b?

Answer 1

Pythagorean Theorem -

$a^{2} + b^{2} = c^{2}$

1 - Input the values!

$9^{2} + x^{2} = 18^{2}$

2. Find the exponents!

$81 + x^{2} = 324$

3. Multi step Equations!

$81 - 81 = 0 \\ 324 - 81 = 243$

4. Use square roots to find x!

$x = \sqrt{243}$

Answer: X=The Square Root Of 243

Answer 2

Answer:

b = 15.59

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + b^2 = 18^2

81 + b^2 = 324

-81             -81  

b^2 = 243

b = 15.59
