To solve this problem you must apply the proccedure shown below:
1. You need to apply the Pythagorean Theorem:
[tex]c^{2}=b^{2}+a^{2}[/tex]
Where c is the hypotenuse and the legs are a and b.
2. Now, you must substitute the values given in the problem above and solve for b:
[tex](2b)^{2}=b^{2}+12^{2}\\4b^{2}=b^{2}+144\\4b^{2}-b^{2}=144\\3b^{2}=144\\b=\sqrt{\frac{144}{3}}\\b=6.92[/tex]
Therefore, the answer is: The value of b is 6.92
Answer:
b= (square root of)48
Step-by-step explanation:
Use pythagoreon theorem,
and you get b^2=48
