Answer:

10.8 =x

Explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

8.8 ^2 + 6.2 ^2 = x^2

77.44+38.44=x^2

115.88=x^2

Take the square root of each side

10.76475731=x

Round to 3 significant figures.

10.8 =x
