Answer:
use d e s m o s it helps with calculations and stuff
Step-by-step explanation:
Using Pythagorean’s theorem, the side length is sqrt(89)
44 = 11
---- ----
p 5
Cross multiply
44*5 = 11p
You end up with ;
220 = 11p
Divide 220 by 11 to get p by itself
20 = p <-- that's your answer
hope i helped :)
The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.
The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:
A = s²
36 sq. units = s²
√(36 sq. units) = √s²
6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)
Therefore, ...
P = 4s
P = 4(6 units)
P = 24 units is the perimeter of a square whose area is 36 square units
No. For two lines to be perpendicular their slope must be the negative reciprocals of one another, mathematically:
m1*m2=-1
So if the slope of one line is negative, the line perpendicular to this must be positive by definition.
