Answer:

8.62

Step-by-step explanation:

Use the Pythagorean theorem.

b= [tex]\sqrt{c^{2}-a^{2} }[/tex]

b=[tex]\sqrt{10.5^{2}-6^{2} }[/tex]

b= [tex]\sqrt{110.25-36[/tex]

b=[tex]\sqrt{74.25}[/tex]

b= 8.62
To solve you have to use Pythagorean Theorem:
a^2+b^2 = c^2
You’re looking for b so the formula would be:
b^2 = c^2-a^2
10.5^2-6^2
110.25-36
74.25
The square root for 74.25 is 8.61684396...
But it tells you to the nearest tenth so the answer would be 8.6
