Answer:

To convert from a decimal to percent, multiply a decimal by 100 and add the percent sign.

Example: 0.10 becomes 0.10 x 100 = 10%

Example: 0.22 becomes 0.22 x 100 = 22%

To convert from a percent to a decimal, divide a percent by 100 and remove the percent sign.

Example: 10% becomes 10/100 = 0.10

Example: 22% becomes 22/100 = 0.22

Hope this helps!

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}
