The diagonal of rectangle ABCD measures 2 inches in length.
What is the length of line segment AB?
3
1 inch
B
60°
03 inches
04 inches
43 inches
2
30
D

B. √3 inches

Step-by-step explanation:

Apply trigonometry ratio to solve for AB

AB = DC (opposite sides of a rectangle are equal)

Given,

reference angle (θ) = 30°

Hypotenuse = BD = 2

Adjacent = DC = ?

Apply CAH, which is:

Cos θ = Adj/Hyp

Substitute

Cos 30° = DC/2

2*Cos 30° = DC

2*√3/2 = DC (Cos 30° = √3/2)

DC = √3 in.

AB = DC. Therefore,

AB = √3 inches

answer: add the !

step-by-step explanation: then we will answer

the answer is 62.8 cubic units
