[patent monolith]

what have you tried so far?

[ember bloom]

Take the ratio of the perpendicular to the hypotenuse

Then equate to tan

And angle of depression is the top right angle, you can figure that out

[vocal violet]

if tried tan^-1(opp/adj) but idk what angle i need to work out, idk what the angle of elevation is

[ember bloom]

The angle of elevation is basically the angle subtending the base to the top

[vocal violet]

what angle is it asking me to work out? what angle is the elevation of r to t

[ember bloom]

If the rectangle was labelled it would be easier for me to explain

[vocal violet]

does that help?

[ember bloom]

Yes, here Angle TRY is the angle of elevation

And angle RTX is the angle of depression

By the way, the angle will come around to be around 64.11 degrees

From calculator

[vocal violet]

so i need to do tan^-1(340/165) ?

tan angle being opp/adj

[ember bloom]

Yes

[ember bloom]

This comes out to be 64.11297373367331170777083112472970203

Degrees

You'll need a calculator for this step
