Answer:
<h3>
d = - 4</h3>
Step-by-step explanation:
<h3>
</h3>
This rule is applied to triangles to determine the unknown sides and angles. The value of x from the diagram is 11.78m
<h3>Trigonometry rule</h3>
This rule is applied to triangles to determine the unknown sides and angles.
Given the following parameter
Opposite = 5m
Adjacent = x
angle = 23 degrees
According to the theorem of tangents
tan23 = opposite/adjacent
tan23 = 5/x
x = 5/tan23
x = 11.78m
Hence the value of x from the diagram is 11.78m
