Help me for 10 years of luck

Answer 1

Answer:3.6cm

Explanation:

tan of an angle is defined as the ratio of the opposite and adjacent.

For the angle
`20^(0)`,the adjacent side is of length
`10cm` and opposite side is of length
`x`.

Let the length of opposite side be
`o` and length of adjacent be
`a`.

`tan(20^(0))=(o)/(a)`

`=(x)/(10)`

Approximate value of
`tan(20^(0))` is
`0.364`

So,
`(x)/(10)=0.364`

So,
`x=3.6cm`
