Question

Can some one help me solve that problem of trig ratio mix

Answer 1

x ≈ 14.3 cm

Explanation:

using the tangent ratio in the right triangle.

tan35° =
`(opposite)/(adjacent)` =
`(10)/(x)` ( multiply both sides by x )

x × tan35° = 10 ( divide both sides by tan35° )

x =
`(10)/(tan35)` ≈ 14.3 cm ( to the nearest tenth )
