piece a has a greater length than piece b (a>b)
If a piece of wire was cut into 2 pieces in the ratio 7:8 and the shorter piece was 14cm, then the length of the longer piece will 16cm.
Write an equation and solve it. Call the length of the shorter piece "x", in this case, the longer piece is "3x". The sum of the two is equal to 116 inches.
x the length of the shorter piece 3·x the length of the longer piece x + 3·x the length of the whole board = 4·x = 76" x = 76" / 4 = 19.
The hypotenuse is the longest side in a right-angled triangle.You can calculate this in different ways depending on what pieces of information you have.If you have the lengths of the two shorter sides, you can use Pythagoras.Or if you have a side and an angle then you may be required to use Trigonometry.
