<h3>Define professional major league baseball (MLB).</h3>

Major League Baseball (MLB), the world's oldest significant professional sports league, is a baseball-related organization. In MLB, there are 30 clubs in each of the National League and American League, with 29 of them being headquartered in the United States and one in Canada. The National League and the American League were started, respectively, in 1876 and 1901. The two leagues came to an agreement in 1903 called the National Agreement, and they have collaborated ever since. They were nonetheless legally distinct entities until 2000 when they united to create a single entity under the direction of the Baseball Commissioner.

10 points someone help me please!?
Soloha48 [4]

Answer:

\large\boxed{b=\sqrt{95}}

Step-by-step explanation:

Use the Pyhagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=b,\ leg=7,\ hypotenuse=12

Substitute:

b^2+7^2=12^2

b^2+49=144       <em>subtract 49 from both sides</em>

b^2=95\to b=\sqrt{95}
