Question

A right triangle’s legs are 3 and 4 meters long. What is the measure of the angle adjacent to the 4-meter leg to the nearest tenth of a degree?

Answer 1

3 is the opposite side, 4 is the adjacent side. Since you have the opposite and the adjacent, you will use the tangent function.
\[\tan(x)=\frac{opp}{adj}\]
\[\tan(x)=\frac{3}{4}\]
then you use the inverse tangent function
\[x=\tan^{-1}(\frac{3}{4})\]

Answer 2

my calculator doesnt let me do the inverse only the regular of tan

Answer 3

Use the one on your computer.
Click "View" and then "Scientific"

Answer 4

it still doesnt show me the inverse it only has tangent and hyperbolic tangent

Answer 5

There is a button that says "Inv"

Answer 6

there isnt a inv symbol only an in symbol that stands for infinity
