Question

In the diagram, rectangle ABCD is split in half by AC. What is the value of tan x?

A. 3/4
B. 4/5
C. 3/5
D. 5/4
E. 4/3

Answer 1

E

Explanation:

Since rectangle have 90 degree angles, Angle D is a 90 degree angle.

Side CD is 3

AD is 4

We found both of those using the definition of rectangle.

`\tan(x) = (opp)/(adj)`

`\tan(x) = (4)/(3)`

E is correct
