Answer:
The answer is 10.2
Step-by-step explanation:
This question wants you to use the Pythagorean Theorem
The Pythagorean Theorem is A^2+B^2=C^2
In this case you can substitute A for 11 and C for 15
If you do some algebra and make the equation B^2=C^2-A^2 or B^2=15^2-11^2
You can simplify and solve now.
B^2=225-121
B^2=104
B=[tex]\sqrt{104}[/tex]
