Answer is b or c I’m pretty sure hope you get it correct
Set up a ratio:
10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.
Cross multiply:
10 * 18 = X * 15
Simplify:
180 = 15x
Divide both sides by 15:
x = 180 / 15
x = 12
The elephants shadow was 12 feet long.
Try 122.
<h3 />
Step-by-step explanation:
Since <em>x</em> = 1, x^6 = 1.
Since <em>y</em> = 11, 11^2 = 121.
1 + 121 = 122.
<h3 /><h3>
So, the value of <em>
x</em>
^ 6 + <em>
y </em>
^ 2 = 122.</h3><h3 />
We will prove first that PRQ≡PSQ
We need 3 attributes from the each triangle:
QS=QR
PR=PS
PQ=PQ
from PRQ≡PSQ => angles RPQ and SPQ are equal
Let if be O=RS∩PQ
We will prove that triangles RPO≡SPO
We need 3 attributes from the each triangle:
RP=PS
PO=PO
angles RPQ and SPQ are equal
results that angles RPO and SPO are equal(Let's note them with x)
We also know that (as angles) POS≡ROS and POR≡SOQ as opposite angles
We now have than 4x=360 wich means x=90. And we proved the desired result.
You just need to put this explanation into the table. (most if the 3 attributes for each triangle)
