In the right triangle shown, ZA = 30° and AB = 4V3.
How long is AC?
Answer exactly, using a radical if needed.

The length of AC is 8

Explanation:

Given that ABC is a right angled triangle.

The measure of angle A is and

Length of AC:

Using the trigonometric ratios, we have,

where and

Substituting the values, we have,

Multiplying both sides of the equation by AC, we get,

Multiplying both sides by , we get,

Simplifying, we get,

Thus, the length of AC is 8

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
