In a right angles triangle the sides are named the hypotenuse (the side opposite the right angle) and the other two sides are called the adjacent and the opposite sides.
1) The sine of an angle = length of the opposite side ÷ length of the hypotenuse.
2) The cosine of an angle = length of the adjacent side ÷ length of the hypotenuse.
Using 1) The length of the hypotenuse = length of the opposite side ÷ the sine of the angle.
Using tables or a calculator obtain the sine of the angle and divide this into the length of the opposite side. The result will be the length of the hypotenuse.

What is the sine if the opposite is 12 and the hypotenuse is 37?
sin of an angle is = the opposite side divided by the hypotenuse the opposite side divide by the hypotenuse = 12 / 37 = 0.324324 to find the angle take the inverse sine of 12 / 37 sin-1(0.324324) = 0.330297 radians, which is equivalent to 18.9246 degrees
How do you find the unknown side of a right triangle given the length of another side and an angle?
opposite/hypotenuse = sin(x) adjacent/hypotenuse = cos(x) opposite/adjacent = tan(x) where 'x' is the angle in question.
If this is opposite is 30 degree angle in a right triangle is 12.5 meters how long is the hypotenuse rounding to the nearest tenth?
If the angle opposite the side of 12.5 meters is 30 degrees then use the sine ratio to find the hypotenuse which works out as 25.0 meters.
How do you find the sin of a triangle?
Sin is opposite over hypotenuse. Just think of this to help you: SOH-CAH-TOA Sine = opposite over hypotenuse Cosine = adjacent over hypotenuse Tangent = opposite over adjacent Hope that helps you.
How do you find the length of a hypotenuse?
To find the length of a hypotenuse (the side of a triangle opposite to the right angle) you need the two shorter sides lengths which i will call A and B. X2=A2+B2 X2=A+B X2=(A+B) X=Find the square root of (A+B) X=The square root of (A+B)
