does someone mind helping me with this question? Thank you!

Answer:
I dont mind :D These were my favorite! They are actually really simple. Dont overthink it. It even gave you a hint!
It says a^2 + b^2 = c^2
We can substitute what we do have which is a = 10 and c = 15
10^2 + b^2 = 15^2
Now we square it
100 + b^2 = 225
Next, all we have to do is subtract the 100 from our answer so 225-100 which is 125, so b has to be 125!!! Because 125 + 100 is 225 :D
Step-by-step explanation:
The length of "b" using Pythagoras Theorem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {10}^{2} + {b}^{2} = {15}^{2} [/tex]
[tex]b = {15}^{2} - {10}^{2} [/tex]
[tex] {b}^{2} = 125[/tex]
[tex]b = \sqrt{125} [/tex]
[tex]b = 11.18033989[/tex]
[tex]b = 11.2 \: (nearest \: tenth)[/tex]
Therefore, the length of "b" is 11.2
