You have to use Pythagoras' Theorem to calculate the hypoteneuse.
It is opposite the right angle of the triangle.
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).
Square root 1.25
You don't. A rectangle doesn't have a hypoteneuse, only a right-angled triangle has a hypoteneuse. As for the diagonal of a rectangle, you can draw it from any vertex to the opposite vertex. It's length is the square root of the sum of the squares of the longer and the shorter side-lengths.
This can only be solved, as far as I know, by trial and error. The square on the hypoteneuse of a right-angled triangle is equal to the sum of the squares on the two adjacent sides. The square on the hypoteneuse, in tis case, is 532 = 2809 Trail and error suggests that one of the sides is 28 -(282 = 784) and the other is 45 -(452 = 2025). Now that we have two adjacent sides we can calculate the area = 28 x 45 = 1260 sq in.
the square on the hypoteneuse is equal to the sum of the squares on the other two sides.
Use the definition of sine as opposite side divided by hypoteneuse. For this problem, the length of side AB equals 2 times the sine of angle C.
I believe it means sides like each other on different objects - as in two triangles - each has a hypoteneuse.
Pythagoras found out that if a triangle is right-angled then the hypoteneuse (long side) squared = the other 2 sides squared and added together
Providing that it is a right angle then use Pythagoras' theorem:- 32+62 = 45 and the square root of this is the hypotenuse which is about 6.708203932
