E and A
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
2x = 6+14
2x = 20
x = 10
We have
The rational root theorem suggests that other possible roots may be -6, 6, -3, 3, -2, 2, -1, and 1. It turns out that is a root, since , so is also a factor and we have
Finally, we can factorize the remaining quotient easily:
so the other factors are , , and .
Answer:
474.84 ft of fencing is needed
Step-by-step explanation:
We know that the angles of a triangle sum up 180º. We already know 2 of the triangle's angles (55º and 63º). Therefore the third angle measures:
180 - 55 - 63 = 62.
To know how much fencing is needed, we need the perimeter of the triangle, so we need to find out how much the other sides of the lot measure.
We will use law of sins to solve this problem.
First we solve for y:
Now we solve for the other side of the lot, x:
Now that we have the measures of all the sides we sum them up
total fencing needed= 150 + 163.16 + 161.68 = 474.84
