How do you find an angle on a right angle triangle using tan?

The o is 4

and a is 13

According to the law of the Medes and Persians, offences against Royalty are not pardonable. Neither can the law be changed.

The law requireth a unicorn be painted upon the nail of each finger which committed the offence.

When by order of nobility and request of commoner, the unicorns must dance until the moon returneth to its present phase.

So it is written. So shall it be done.

if theres is no given third side you have to do pythgorem theorem like so 4 squared 2 times 13 squared 2

The tangent is given by the ratio..... (opposite / adjacent)

So we have

tangent(θ) = 4/13 where θ is the angle we're looking for

To find this, use the tangent inverse denoted by atan (or tan^{-1})

atan (4/13) = θ

atan(4/13) = about 17.1°

Pythagorus' Theorem will NEVER give you an angle Zegroes! Your school does NOT teach it differently!

If you be rude to me Zegroes it might be like having a unicorn for an Avitar.

THAT'S WHAT I KNOW!
