How do you find the hypotenuse of a triangle without Pythagoras theroem?
You need a side and another angle. Hypo = side / sin angle. Eg if a side is 6 units and an angle 30 degrees then hypotenuse = 6/0.5 = 12
The hypotenuse of a 30-60-90 triangle has length 19 What is the length of the side opposite the 60 angle?
If the hypotenuse of a 30-60-90 triangle has a length of 19, the length of the side opposite the 60 degree angle is: 16.45. (the other leg would be 9.5)sine 60 degrees = opposite/hypotenuseOpposite = 19*sine 60 degreesOpposite = 16.45448267 or 16.45 units to two decimal places
If you divide length of the adjacent side of an angle in a right triangle by the length of the hypotenuse what value do you get?
Adjacent Side / Hypotenuse = Natural Cosine of the Angle. For example: Adjacent Side=20cm / Hypotenuse=40cm = 0.5 Look up 0.5 in a Natural Cosine table and look back to the degrees on the left margin, you'll find 60... 60 degrees is the angle between the hypotenuse and the adjacent side.
What does sin in maths mean?
sin issinusIn a triangle with a 90 degrees angle, the sinus of an angle is defined as the ratio between the lenghts of the side at the opposite of the angle, and thehypothenuse, the longest side.sin (alpha) = opposite length / hypothenuse length.
What are the lengths of the legs of a right triangle in which one acute angle measures 19 and the hypotenuse is 15 units long?
The side opposite the angle 19 degrees is given by 15sin 19 = 4.9 units, while the side adjacent the angle 19 degrees is given by 15cos 19 = 14.2 units. So answer = 4.9 units, 14.2 units.
How do you construct a 30 degree angle without the use of a protactor?
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.

What is the approimate side length of a square with a diagonal of 5 units?
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
What is the longest length of a trangle when its shortest length is 3.6cm if two of its angles are 37.25 degrees and 48.4 degrees?
The longest side is opposite to angle 94.35 degrees The shortest side of 3.6cm is opposite to angle 37.25 degrees The longest side is 3.6*sin(94.35) divided by sin(37.25) = 5.93cm
What is angle if sin equals 0.99?
If the sine of an angle is 0.99, then the angle is approximately 84.3 degrees. This is because the sine function gives the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. In this case, the opposite side is much longer than the hypotenuse, indicating a steep angle close to 90 degrees.
What is the 3rd angle and the lengths of its two other side of a triangle having a length of 12 cm from angle 73 degrees to angle 59 degrees?
Let the sides be a b c and their opposite angles being A B C and so:- 3rd angle: 180-73-59 = 48 degrees Using the sine rule the length of side b = 13.8 cm Using the sine rule the length of side c = 15.4 cm

What is the length of the opposite side of a right triangle that has an angle of 35 degrees and a hypotenuse of 20?
The side opposite the 35° angle is [ 20 sin(35) ] = 11.472 (rounded)
How do you classify by it measure of its angles and the lengths of its side?
Angle Classifications:Obtuse (1 angle >90 degrees)Acute (all 3 angles
How do you convert sine to degrees?
Sine can be found in degrees by taking the length of the opposite side and hypoteneuse. Then divide the opposite side by the hypoteneuse. Any calculator can be used to find this. for example, if the hypoteneuse side was 7, and the opposite side was 3, and you labeled the angle "A", then it would be "sineA= 3/7" ...... then A=sin^-1 (3/7) and you put that in your calculator and the answer you get is the angle in degrees (if the calculator is in degrees mode, and if the angle is an acute angle).
