200.6ft
Step-by-step explanation:
- find the area of the square that is L².=12²ft which is 144ft
- the area of the half a circle which is 1/2πr²which is 1/2×22/7×6²=56.6 after rounding of to one decimal place
- add the two areas 144+56.6=200.6ft
When triangles are similar, ratios of corresponding side lengths are the same. The side lengths you know are CD, DU, VW, WU. (You also know CU, but you do not know the corresponding length VU.)
The ratios can be formed in any convenient way, but it is already clear that the triangles are not similar. CD = 73 is a prime number, and neither DU nor VW is a multiple of that. For example, ...
... CD/VW = 73/84 ≠ 48/55 = DU/WU
Given <span>x-3/4=x/10 find the LCD. It is 20, as both 4 and 10 divide evenly into 20.
Then you have 20x - 15 = 2x, or 18x = 15, or x = 15/18, or x =5/6 (answer).</span>
