Question

What is the value of x in the nearest whole number​

Answer 1

Answer:

16

Step-by-step explanation:

To calculate x we must use the trig function of tangent:

as tangent is opposite divides by adjacent we can get this equation:

$\tan 30 = \frac{9}{x}$ which is equal to:

$x=\frac{9}{\tan 30}$ So x must equal to 15.588.. (just put the second bit in the calculator

As all the values provided are integers you round this to the nearest whole number:

16 (as the third digit, 5, rounds up)

so our answer is 16
