Question

Determine the measure of x

Answer 1

The value of x is 41.1 units .

Explanation:

You have to use Cosine Rule, cosθ = adjacent/hypotenuse. Then substitute the following values into the formula :

`\cos(θ) = (adj.)/(hypo.)`

Let θ = 47°,

Let adj. = 28,

Let hypo. = x,

`\cos(47) = (28)/(x)`

`x \cos(47) = 28`

`x = (28)/( \cos(47) )`

`x = 41.1 \: units \: (3s.f)`
