Answer:
366.6 mm²
Step-by-step explanation:
Step 1: find XY using the Law of sines.
Thus,

m < W = 180 - (70+43) (sum of angles in a triangle)
W = 180 - 113 = 67°
WY = 24 mm
X = 43°
XY = ?

Cross multiply:


Divide both sides by 0.68 to solve for XY


XY ≈ 32.5 mm
Step 2: find the area using the formula, ½*XY*WY*sin(Y).
Area = ½*32.5*24*sin(70)
Area = ½*32.5*24*0.94
= 32.5*12*0.94
Area = 366.6 mm² (nearest tenth)
16y = 164
y = 164 ÷ 16
y = 10.25

Answer:
m = 12.728 or 18/root (2)/2, n = 9
Step-by-step explanation:
To find m, we can use sin(45) and cos(45).
Since sin(45) = root (2)/2 and this equals 9/m.
We set the equation root (2)/2 = 9/m and solve for m.
9 divided by root (2)/2 would give us 18/root (2), or 12.728.
m is 12.728.
Same process for n but we are using cosine this time.
cos(45) = root (2)/2 and this equals n/12.728.
Solving for n would give us root (2)/2 times 12.728.
This gives us that n is 9.
If the population was 40,000 at the beginning of 2009, at the end of 2009 it has increased by 10% and became 44,000.
By the same way, at the end of 2010, it became

At the end of 2011, the population was
