Question

Answer Part A and Part B for the triangle shown

Answer 1

for Part A

Answer is C.

Explanation:

`\tan(a) = (opposite)/(adjacent ) \\`

Here the angle, a is 60°, Opposite is 20 and adjacent is x.

Therefore we have,

`\tan(60 ) = (20)/(x)`

Making x the subject gives us

`x = (20)/( \tan(60) )`

Part B

Value of x to the nearest tenth

`x = 11.547 \\ to \: the \: nearest \: tenth \\ x = 12`
