a corner of a cube connects 3 sides to each other,
then add the side of the cut
so it would have 4 sides
Answer:
![y=2\sqrt{10}](https://tex.z-dn.net/?f=y%3D2%5Csqrt%7B10%7D)
Step-by-step explanation:
By applying geometric mean theorem in the given right angle,
![\frac{AD}{DB}=\frac{DB}{CD}](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BDB%7D%3D%5Cfrac%7BDB%7D%7BCD%7D)
By substituting values in the given ratio,
![\frac{5}{y}= \frac{y}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7By%7D%3D%20%5Cfrac%7By%7D%7B8%7D)
![y^2=8\times 5](https://tex.z-dn.net/?f=y%5E2%3D8%5Ctimes%205)
![y^2=40](https://tex.z-dn.net/?f=y%5E2%3D40)
![y=2\sqrt{10}](https://tex.z-dn.net/?f=y%3D2%5Csqrt%7B10%7D)
Exact value of y is
.
Answer: 3,750 miles
Step-by-step explanation:
Route takes him 125 miles each way so in a day he travels:
= 125 + 125
= 250 miles
He made 15 roundtrips so total miles is:
= 15 * 250
= 3,750 miles
Answer:
27
Step-by-step explanation:
You add 63 and 90 (90 being the right angle) and then subtract that from 180 which is the sum of all three angles and you get 27.
