1 Let the sides be 5x and 12x
2 Using Pythagoras' theorem: (5x)2+(12x)2 = 22.752
3 So: 25x2+144x2 = 517.5625 => 169x2 = 517.5625
4 Divide both sides by 169 and then square root both sides
5 Therefore: x = 1.75 so sides are 5*1.75 = 8.75 cm and 12*1.75 = 21 cm
6 Area = 0.5*8.75*21 = 91.875 square cm
Sine ratio = opposite/hypotenuse
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
It is: sine = opposite/hypotenuse
A TRIGONOMIC ratio is a ratio between either the opposite side of an angle and the hypotenuse of a triangle (sine), the adjacent side of an angle and the hypotenuse of a triangle (cosine), or the opposite side of an angle and the adjacent side (tangent). Mnemonic: SOH CAH TOA S= sine C= cosine T= tangent O= opposite A= adjacent H= hypotenuse
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
Fora right angle triangle: cosine angle = adjacent/hypotenuse
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
It means the ratio of the opposite angle to the hypotenuse of a triangle for angle "x". This is for a right triangle.
Sine ratio = opposite/hypotenuse
False because sine ratio = opposite/hypotenuse
If you mean cosine then it is angle ratio found in a right angle triangle which is adjacent/hypotenuse
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
It is the 'sine' ratio for a right angle triangle
It is: sine = opposite/hypotenuse
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
