Sine = Opposite / Hypotenuse = 30 / 90 = 1/3 ~= 0.33 To remember the ratios, I was taught 2 mnemonics: Each letter of SOHCAHTOA represents a ratio: Sin = Opposite / Hypotenuse Cos = Adjacent / Hypotenuse Tan = Opposite / Adjacent Prior to secondary school where I was taught that, I was taught this rhyme, which I much prefer: Two Old Arabs Soft Of Heart Coshed Andy Hatchett Again, each initial letter shows the ratios. Tan = Opposite / Adjacent Sin = Opposite / Hypotenuse Cos = Adjacent / Hypotenuse

The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).

Calculator in degree mode. tanX = opposite/adjacent so... tan30 degrees = height/275 meters = 159 meters tall

The length of the line adjacent to angle 45 degrees will also be 12.5 meters because in effect the given triangle is that of half a square with 4 equals sides of 12.5 meters or alternatively using trigonometry 12.5*tangent(45) = 12.5 meters

The hypotenuse is: 10

It's also 12.5 meters. The two sides of the triangle are the same length, because it is an isosceles right triangle(90-45-45).

The side adjacent to the forty degrees of a right triangle with a hypotenuse of 6 meters and one of its angles measuring forty degrees is: 4.6 meters.

If a right triangle is 12.5 meters and the side opposite a 30 angle, the hypotenuse length will be: 14.43 meters.

When two sides of a right triangle are 6 and 8, the triangle is similar to a 3-4-5 right triangle. Since 6 is twice 3 and 8 is twice 4, the hypotenuse has to be twice 5 or 10.

If the side opposite a 30 degree angle in a right triangle is 12.5 meters, the hypotenuse is: 25 meters.25 meters
