Question

I need some help, please! Find the value of x and round to the nearest tenth.

Answer 1

1.6

Explanation:

observing the figure and applying Pythagoras theorem in triangle

`x = √(2.1^2 - 1.4^2)`

`x = √(4.41 - 1.96)\\x = 1.57`(rounded to nearest hundredth)

x = 1.6 (nearest tenth)

Hopefully this answer helped you!!!
