Sharon is assessing the popularity of two fashion magazines for her blog. The number of subscribers to magazine A and the number
of subscribers to magazine B for the years 2000 to 2004 are given in the tables below.
The number of subscribers to magazine A in 2000 is 5,000, 20,000, 25,000, or 10,000 more, or less than the number of subscribers to magazine B in 2000.
Which of the following describes the number of subscribers represented by the tables? Only the number of subscribers to magazine B is increasing. , The numbers of subscribers to both magazines are increasing. , The number of subscribers to both magazines are decreasing. , or Only the number of subscribers to magazine B is decreasing.
As the number of years since 2000 increases, the number of subscribers to only magazine B approaches infinity, only magazine A approaches zero, only magazine A approaches infinity, only magazine B approaches zero, both magazines approach negative infinity, or both magazines approach zero .

Answer:
Y = 32.7°
Step-by-step explanation:
We will apply the Cosine law in the given triangle XYZ,
x = 90 ft
y = 55 ft
z = 50 ft
We have to find the measure of angle Y.
y² = x² + z² - 2xzCosY
(55)² = (90)² + (50)² - 2(90)(50)cosY
3025 = 8100 + 2500 - 9000.cosY
9000.cosY = 10600 - 3025
cosY =
= 0.84167
Y =
Y = 32.68 ≈ 32.7°
Therefore, measure of angle Y = 32.7°
