Answer:
B.) 10
Step-by-step explanation:
You could use the distance formula to calculate the length of AB, I prefer a visual approach, because it requires less memorization.
Draw a vertical line from B and a horizontal line from A until they intersect at D (5, 4).
Then you have a right triangle ABD, and you can use Pythagoras' theorem to calculate AB.
Answer:
sin(x)= / 12, cos(x)=5/12, tan=
/ 5
Step-by-step explanation:
segment YZ is length a, we need to find a
segment XZ is length 5
segment XY is length 12
XYZ is a right triangle, so a^2 + b^2 = z^2, so
a^2 + 5^2 = 12^2, simplify
a^2 + 25 = 144, subtract 25
a^2 = 119
a =
then we can determine all the trig ratios
soh - cah - toa
sin = opp/hyp, cos=adj/hyp, tan=opp/adj
sin(x)= / 12, cos(x)=5/12, tan=
/ 5
