Find the value of x to the nearest tenth

lorasvet [3.4K]

Answer:

Look below.

Step-by-step explanation:

Good ol' Pythagorean Theorem.

To find the short side of the larger triangle, we'll use this equation:

$a^{2} +b^{2} =c^{2} \\\\9^2+b^2=10^2\\81+b^2=100\\$

You can solve the rest on your own.

Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

$3^2+x^{2} = b^2$

Hope it helped! Also, there seems to be a help video, if you didn't understand this explanation, why don't you go ahead and watch it?
