Answer:
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:
This can be written 8^(4/3)=(∛8)⁴=2⁴=16.
