Answer:

a = 4\sqrt{3}

b= 4

Step-by-step explanation:

It's a 30-60-90 triangle based on the given picture. A right triangle too

Use sine, cosine, and tangent to solve for the side.

To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.

OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and x\sqrt{3} for long leg

So either way, b = 4

To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.

OR you can use the same rule, 30-60-90 triangle to save time

a will end up = 4\sqrt{3}

Guys this makes no sense someone help!! The amount of money raised at a charity fundraiser is directly proportional to the numbe
svlad2 [7]

A)

The formula for direct variation is written as Y = kx, where k is the proportion you need to solve for.

Y would be the amount raised and X would be the number of attendees:

100 = k5

Divide both sides by 5:

k = 100/5

k = 20

B. the constant of variation is the value of k above which is 20

C) Using the formula from A: y = kx, replace k with 20 and x with 60 and solve for y:

y = 20 * 60

y = 1200

They will raise $1,200

2. If the relationship is proportional the ratio would be a constant number. If the relationship is non proportional the ratio would vary between the different values.
