Question

Which equation can be used to solve for the measure of angle ABC? tan(x) = 2.4/10 tan(x) =10/2.4 sin(x) =10/10.3 sin(x) =10.3/10

Answer 1

The answer is tan(x)=2.4/10, or A.

Answer 2

we know that

in the right triangle ABC

$tan(x)=\frac{opposite\ side\ angle\ x}{adjacent\ side\ angle\ x}=\frac{AC}{BC}$

in this problem we have

$AC=2.4\ cm\\BC=10\ cm$

substitute the values

$tan(x)=\frac{2.4}{10}$

therefore

the answer is

$tan(x)=\frac{2.4}{10}$
