lowest exponent. The leading coefficient is the coefficient of the first term in a

Answer:

Step-by-step explanation:

Hello,

We can write three equations thanks to Pythagoras

$AB^2+AC^2=(7+3)^2\\x^2+7^2=AB^2\\x^2+3^2=BC^2\\$

So it comes

$x^2+7^2+x^2+3^2=(7+3)^2\\\\2x^2=100-49-9=42\\\\x^2 = 42/2=21\\\\x = \sqrt{\boxed{21}}\\$

Hope this helps
