Answer 1

Explanation:

Use ToA method (tan = opposite / adjacent)

For this question we have to use pythagoras' Theorem to find the adjacent side.

take a as the length of the adjacent side.

given b = 12

c = 13

By pythagoras' Theorem,

`{c}^(2) = {a}^(2) + {b}^(2) \\ {a}^(2) = {c}^(2) - {b}^(2) \\ {a}^(2) = {13}^(2) - {12}^(2) \\ {a}^(2) = 169 - 144 \\ {a}^(2) = 25 \\ a = √(25) \\ = 5`

Now we can find tan(x)

tan(x) = Opposite / adjacent

`= (12)/(5)`
