Answer:
x = 5.6
Step-by-step 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
