The length of BC is (B) 12.
To get the length, we must first find the angle of the triangle using the equation tan θ = opposite/adjacent then we can derive the equation for the angle as θ =

(

). the angle (θ) = 33.69006753. Since they are similar triangles, we can use the same equation to find the length of BC. BC = tanθ*BF; BC =

* 18 and finally we can get BC = 12.
Answer:
A) 150
B)30
Step-by-step explanation:
3. is an obtuse angle and has a measure of 165 degrees
4. is an acute angle and has a measure of 55
The domain is the variation of values that x can equal. In this case, the domain is from 5 to infinity.
Answer:
2) (-2,1)
Step-by-step explanation:
Solve using the substitution method -x-(x+3)=1 using this equation you would find x which is -2
Substitute -2 into the given equation, y=-2+3 y=1
Therefore, The answer is (-2,1)
