CAN SOMEONE PLEASE HELP ME WITH MY MATH ASAP PLEASE!!!

The answer is :

so, type 190 in the box

Step-by-step explanation:

Notice that there are three right angle triangles in the image given. In order to create equations associated with the Pythagorean Theorem for the three triangles, we add the letters x and z to identify two sides that are missing information. Please see attached image for reference.

In the small right angle triangle on the right, the Pythagorean theorem tells us:

In the larger triangle :

In the small triangle on the left:

and in this last equation we can substitute the z-squared and the x-squared by the expressions we got before in the other two equations:

Then to solve for "y" we apply the square root:

x=6 and x=3
