D=51/77
First set up the equation equal to zero(0), the distribute from there.
Answer:
the answer is -8
Step-by-step explanation:
A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.
PQ:
(4-2)/(1-(-3))
2/4
1/2
RS:
(2-0)/(3-1)
2/2
1
Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
Answer A would the one that's false
