I got my maths exam in a couple hours and I can't remember how to work out angles of right angle triangles when given two sides, or how to work out sides when an angle is given. I really need to pass this exam so please help.

just remember this. SOH (Sine of theta = Opposite side / Hypotenuse) CAH(CoSine of theta = Adjacent side/ Hypotenuse) and TOA (Tangent of theta = Opposite / Adjacent side)

then do arc sines, arc cosines, and arc tangents to get the angles in degrees

Use soh cah toa-

sine= opposite/hypotinuse
cosine= adjacent/hyp
tan=opp/adj

Or the sine rule-

A/sinA=b/sinB=c/sinC

Depending on what you've been given.

And it's an exam?

Next time don't leave it till a few hours before the actual test...

Trigonometry. The formulas:

Sine (angle you want) = opposite (side opposite angle you want) / hypoteneuse (longest side, opposite the right angle)

Cosine (angle you want) = adjacent (side next to the angle you want) / hypoteneuse

Tangent (angle you want) = opposite / adjacent

EDIT: Forgot about the sine/cosine/tangent (not really ever used) rules, but every test I've done has had them written out for you.


And who goes to UG for maths help (although for once we have been helpful)?

Good luck!
