Opposite: opposite the angle θ
Hypotenuse: longest side (and opposite the right angle)

• Determine what is given: for example an angle
(Theta) and a side (such the adjacent side)
• Find the match (there are only six possiblities)
• Enter the values and press the "Show" button
• Only put in numbers and a decimal point
• The Hypotenuse is ALWAYS the longest side
• All angles (except the right angle itself)
are less than 90 degrees
• Put in garbage, you'll get out garbage

 Given Value Hypotenuse Theta (in degrees) Use x = r * cos(θ)y*y = r*r - x*x Show Restart
 Given Value Adjacent Theta (in degrees) Use r = x/cos(θ)y*y = r*r - x*x Show Restart
 Given Value Opposite Theta (in degrees) Use r = y/sin(θ)x*x = r*r - y*y Show Restart
 Given Value Adjacent Hypotenuse Use θ = arccos(x/r)y*y = r*r - x*x Show Restart
 Given Value Opposite Hypotenuse Use θ = arcsin(y/r)x*x = r*r - y*y Show Restart
 Given Value Opposite Adjacent Use θ = arctan(y/x)r*r = x*x + y*y Show Restart
