Answer 1

5.6

........................................................................

Answer 2

x = 5.6

Explanation:

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

a^2+b^2 = c^2

4.8 ^2 + x^2 = 7.4^2

23.04 +x^2 =54.76

Subtract 23.04 from each side

x^2 = 54.76 - 23.04

x^2 =31.72

Take the square root of each side

x =5.632051136

Rounding to the nearest tenth

x = 5.6
