Answer:
K = 10
Step-by-step explanation:
Interior angle adjacent to y = 180-115 = 65
Sum of interior angles in a triangle = 180
This the remaining interior angles for the triangle = 180-65= 115
In other words,
4K+5+6k+10 = 115
Simplify and solve:
10k + 15 = 115
10k = 115-15=100
K= 100/10 = 10
Hope this helps.
Good Luck
Answer:
a. 199,389
b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
Step-by-step explanation:
a. Population in 2009 = 192,370
This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389

Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
