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 :
[tex] \cos(θ) = \frac{adj.}{hypo.} [/tex]
Let θ = 47°,
Let adj. = 28,
Let hypo. = x,
[tex] \cos(47) = \frac{28}{x} [/tex]
[tex]x \cos(47) = 28[/tex]
[tex]x = \frac{28}{ \cos(47) } [/tex]
[tex]x = 41.1 \: units \: (3s.f)[/tex]
