Question

Determine the measure of x

Answer 1

Answer: 43 degrees

Step-by-step explanation:

Answer 2

Answer:

The value of x is 41.1 units .

Step-by-step explanation:

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

$\cos(θ) = \frac{adj.}{hypo.}$

Let θ = 47°,

Let adj. = 28,

Let hypo. = x,

$\cos(47) = \frac{28}{x}$

$x \cos(47) = 28$

$x = \frac{28}{ \cos(47) }$

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