Question

Use a triganonimic ratio foto find the value of x

Answer 1

Explanation:

from;tan(40)=opp/hyp

so ,tan(40)=4/x

x=4/tan(40)

x=4/0.7265

x=5.5055

to the nearest tenth x=5.5

Answer 2

x ≈ 4.8

Explanation:

using the tangent ratio in the right triangle

tan40° =
`(opposite)/(adjacent)` =
`(4)/(x)` ( multiply both sides by x )

x × tan40° = 4 ( divide both sides by tan40° )

x =
`(4)/(tan40)` ≈ 4.8 ( to the nearest tenth )
