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

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
