Question

Find the missing side. triangle trig

Answer 1

see below; round to the correct number of digits (I couldn't see this part)

Explanation:

cos(28°) = x / 14

x = 14cos(28°) ⇒ calculator

x ≈ 12.3612663

Answer 2

x ≈ 12.36

Explanation:

using the cosine ratio in the right triangle

cos28° =
`(adjacent)/(hypotenuse)` =
`(x)/(14)` ( multiply both sides by 14 )

14 × cos28° = x , that is

x≈ 12.36 ( to 2 dec. places )
