Answer:
A and D both have a value of -4
Step-by-step explanation:
A. (-4) = -4
B. |-4| = positive value of what is inside = 4
C. |4|
= positive value of what is inside = 4
D. -|4| = -positive value of what is inside = -4

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the side "?" is the Adjacent side (Adj) and we are given the angle and the Hypontenuse ( long side) (Hyp) of this triangle
so use CAH
cos(75) = Adj / 8
algebra to solve for the Adj side (which is the "?" for this problem )
8*cos(75) = Adj
2.07055 = Adj
so the "?" is 2.1 ft ( rounded to the nearest 10th )
Using the distance formula I got 10.81665383 : 10.82
