The area of all paralellograms can be found by
area=base times height
so
area=26 and 1/2
height=6 and 5/8
convert to improper fractions for ease of use
26 and 1/2=52/2+1/2=53/2
6 and 5/8=48/8+5/8=53/8
so
area=height times base
53/2=53/8 times base
multiply both sides b 8/53 so that we clar the fraction (53/8 times 8/53=424/424=1)
(53 times 8)/(53 times 2)=1base
8/2=1base
4=base
answer is base=4 units

Answer:
C
Step-by-step explanation:
Using the cosine rule
cosZ = 
= 
= 
, thus
Z =

Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,
MrB
