Question

Solve for x. Round to the nearest tenth.
​

Answer 1

Answer:

7.2

Step-by-step explanation:

14 = c

12= b

√(c² - b²)

12 x 12 = 144

14 x 14 = 196

196-144 = 52

√(52) = 7.21110255093

Answer 2

Answer:

x ≈ 7.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 14²

x² + 144 = 196 ( subtract 144 from both sides )

x² = 52 ( take square root of both sides )

x = $\sqrt{52}$ ≈ 7.2 ( to the nearest tenth )
