Find the number that belongs in the green box.
Round your answer to the nearest tenth.

Answer:
9.2
Step-by-step explanation:
Since it is a right triangle, we can use pythagorean theorem to figure out the hypotenuse length.
a^2 + b^2 = c^2
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
square root both sides get
c= 9.219, rounded to nearest tenth is 9.2
