Answer:
79 soldiers
Step-by-step explanation:
Since 40 soldiers were not included in the square, the square consists of 6241 soldiers. 6241 represents the area of the square, and the rows (r) represents a side of the square. Since the area of a square = the length of the side squared, then
.
So 
r = 79
Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.

Subtituting the value in the formula.

⇒ 
⇒ 
Putting square root on both side
We know, √a²= a
⇒ 
∴ hypotenous= 11.18 
Hence, the slope is 11.2 feet
Answer:
The value of PC is 40.
Step-by-step explanation:
Consider the complete question is " C is the circumcenter of triangle PQR. PC=3X-7 RC=5X-15 & QC= 51-X What does PC equal?"
All vertices or a triangle are equidistant from its circumcenter.






The value of x is 11.
We need to find the value of PC.

Substitute x=11 in the above equation.



Therefore, the value of PC is 40.
