One of the properties of rhombus is its sides are congruent. Therefore, we will only need to find the length of one side using the distance formula. At line YZ, the distance is 
D =
= √13
To get the perimeter, multiply one side to 4. Hence, the perimeter is 4√13 (C)
D =

Answer:
1. 30
2. 150
Step-by-step explanation:
Lets assume tan(x) = u
Now we solve for 'u'
add 1 on both sides
, divide both sides by 3
Take square root on both sides
We replace tan(x) for 'u'
x = 30 because in first quadrant
x = 30 (tan is positive in first quadrant)
x = 150 because in second quadrant
tan is negative in second quadrant
