Answer:

[tex]\sqrt{259}[/tex] or approximately 16.09

Step-by-step explanation:

Using the pythagorean theorem, the formula would be [tex]a^{2} + b^{2} = c^{2}[/tex]

insert 15 into a and 22 into c.

you will get [tex]15^{2} + b^{2} = 22^{2}[/tex]

That simplifies into 225 + [tex]b^{2}[/tex] = 484

subtract the 225 from 484 to isolate the variable

then you will get [tex]b^{2}[/tex] = 259

square root both sides to get rid of the square: [tex]\sqrt b^{2}[/tex] = [tex]\sqrt{259}[/tex]

if you want the decimal version, fully square root the number and you will get approximately 16.09 (rounded to the nearest hundredth)
