What is the value of x?
Round to the nearest tenth, if necessary.
O x = 4
O x = 5,8
O x=7
O x=8

Answer 1

x = 5.8 Option 2

Explanation:

AC of length x is the hypotenuse of the right triangle ABC whos other two sides are AB and BC

By the Pythagorean theorem,

AC² = AB² + BC²

Given AB=5, BC = 3 and AC = x

x² = 5² + 3²

x² = 25 + 9 = 34

x = √34 = 5.83 and rounded to the nearest tenth it would be 5.8

Answer:
x = 5.8 Option 2
