Question

Find the value of X round your number to the nearest tenths Explain it please

Answer 1

In this case, we must use trigonometry to find the value of x:

        $tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24$

Thus the value of x rounded to the nearest tenth is 8.2

Hope that helps!
