Answer 1

Answer:
`2061.55\ m`

Explanation:

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

`\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4* 10^6+25* 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km`
