Question

What is the length of line segment AB?
1 inch
v3 inches
4 inches
475 inches​

Answer 1

B

Explanation:

the answer is B on edge.

Answer 2

`AB=√(3)\ in`

Explanation:

The correct question is

The diagonal of rectangle ABCD measures 2 inches in length.

What is the length of line segment AB?

The picture of the question in the attached figure

we know that

In the right triangle ABD

`cos(30^o)=(AB)/(BD)` ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

`cos(30^o)=(AB)/(2)`

Remember that

`cos(30^o)=(√(3))/(2)`

so

`(AB)/(2)=(√(3))/(2)`

`AB=√(3)\ in`
