Either or can be used with any triangle...I personally find the law of sines is often more compact as in this case we can just say;
(sin115)/18=(sin40)/c (with no need for b or B as would be needed with the law of cosines...)
c=18(sin40)/(sin115)
c≈12.77
The answer is 25 which is by multiplying 4/10 and 5/x and the devide by 4
Answer:
x = 6
NO = 26
Step-by-step explanation:
recall that for a rhombus all the sides are of equal length,
which means, PM = MN = MP = NO
we are given
MP = 5x-4 and MN = 6x-10
since MP = MN, thus
5x-4 = 6x-10 (add 4 to both sides)
5x = 6x - 10 + 4
5x = 6x - 6 (subtract 6x from both sides)
5x-6x = -6
-x = -6
x = 6 (answer)
NO = MP = 5x-4 = 5(6) - 4 = 30 - 4 = 26
V=area of base times height
height=height
area of base=area of circle=pir^2
V=hpir^2
r=6
h=14
V=14pi6^2
V=14pi36
V=504pi
aprox pi=3.141592
V=1583.3 round
V=1583 cm^3
If they are 36 together, and Marsha is twice Mary then do 2x+x=36
Saying that Marsha is twice Mary.
