Answer:
a = 20.79cm ( 2 decimal places)
Step-by-step explanation:
find the length of the identical sides (i name it "x") first using Pythagoras theorem
= 
219.04 = 
= 219.04/2 = 109.52
x = 
now find a,
= 
+ 
= 109.52 + 322.7477 = 432.2677
a = 
= 20.791048
Answer:
C. = 69.5
Step-by-step explanation:
The median or the average between 80 and 59 is 69.5
Hope this helps! :)
The perimeter is calculated by adding the lengths of all the sides together, or by using the form P = 2l + 2w
Here, that would be:
P = 2(5) + 2(4)
P = 10 + 8
P = 18
Answer:
P = 18 cm
Hope this helps.
Answer:
(a) |ab| if a<0 and b>0
since the modulus of a number no matter whether it is positive or negative gives the result as a positive number.
if a<0 and b>0 then ab<0
this implies ab is a negative number and modulus of negative number comes out to be positive term.
<em>eg:</em> if a= -2 and b=3
Then ab= -6
and |ab|=|-6|=6
(b) |ab| if a>0 and b>0.
since both a and b are positive numbers i.e. strictly greater than zero.
hence, ab>0
eg: if a=5 and b=2
then ab=10
and |ab|=|10|=10
