Answer:
for Part A
Answer is C.
Step-by-step explanation:
[tex] \tan(a) = \frac{opposite}{adjacent } \\ [/tex]
Here the angle, a is 60°, Opposite is 20 and adjacent is x.
Therefore we have,
[tex] \tan(60 ) = \frac{20}{x} [/tex]
Making x the subject gives us
[tex]x = \frac{20}{ \tan(60) } [/tex]
Part B
Value of x to the nearest tenth
[tex]x = 11.547 \\ to \: the \: nearest \: tenth \\ x = 12[/tex]
