Answer:
24 cm
Step-by-step explanation:
in rhombuses, the rule is that all sides are the same length which means 3x - 6 = x + 14. then, you just have to solve this:
3x - 6 = x + 14
subtract x from both sides
2x - 6 = 14
add 6 to both sides
2x = 20
divide both sides by 2
x = 10.
to find the length of each side, plug this back into the original side length expressions:
3x - 6 becomes 3 * 10 - 6 = 30 - 6= 24 cm
<em>the length is 24 cm.</em>

i know u are using mathswatch i feel your pain but however hard you try you will almost never get the right show your working out
Please see the attached picture to see the similar triangle.
The new triangle has triple the side lengths of the first one. This means all side lengths will be triple.
You will use this ratio to find the new side lengths and then use them to find the perimeter and area.
3:4:5 = 9 cm: 12 cm:15 cm on triangleABC
1. The
perimeter is 9cm + 12 cm + 15 cm or
36 cm.
2. The
area is 1/2 x 12 x 9 or
54 square cm.
3. The length of the
hypotenuse is
15 cm.
