In triangle WXY, the measure of angle Y=90 degrees, XW=89, WY=80, and YX=39. What ratio represents the cosine of angle X?
Answers
Answer: [tex]\dfrac{39}{89}[/tex]
Step-by-step explanation:
Given: In triangle WXY,
∠Y = 90°, XW = 89 units, WY = 80 units and YX = 39 units.
According to trigonometry ,
Cosine of A [tex]=\dfrac{\text{side adjacent to A}}{\text{hypotenuse}}[/tex]
From the figure below,
[tex]\text{cosine of } \angle X=\dfrac{YX}{WX}\\\\=\dfrac{39}{89}[/tex]
Hence, required ratio = [tex]\dfrac{39}{89}[/tex]

Simplify: 4(36)?????
Answers
Answer:
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF). So, 436 = 4÷436÷4 = 19. Thus, 436 is equivalent to 19 in the reduced form.
Step-by-step explanation:
The solution for the expression 4(36) after you simplify can be expressed as 144.
What is 4(36) when you simplify?To simplify the expression 4(36), we need to perform the multiplication operation.
4 multiplied by 36 can be calculated as follows:
4 x 6 = 24 (multiplying the units digit)
4 x 30 = 120 (multiplying the tens digit)
Now, we add the results together:
24 + 120 = 144
Therefore, the number 4 multiplied by the number 36in brackets is equals to 144.

work out a & e

Answers
Answer:
a = 14
b = 15
c = 15
d = 18
e = 18
Step-by-step explanation:
The stratified sampling works as follows:
stratified sampling = (Population of subgroups)*(total sample size)/(entire population)
in this case, sample size = 80
entire population = 140 + 150 + 150 + 180 + 180 = 800
Population sample is the number of students of each year (for year 7, the population of subgroup is 140, and so on)
whith this equation we can find all the missing values:
a = (140)*(80/800) = 14
b = (150)*(80/800) = 15
c = (150)*(80/800) = 15
d = (180)*(80/800) = 18
e = (180)*(80/800) = 18
