99 x .05 = 4.95 in tax
99 + 4.95 = 103.95
Answer:
5/6 - 10/12, 15/18, 20/24
3/8 - 6/16, 9/24, 12/32
Step-by-step explanation:
Start by drawing a right triangle with legs matching the given point.
Horizontal leg = -8, Vertical leg = 3
The hypotenuse should be identical to a line going from given point to origin.
Next, use pythagorean theorem to find length of hypotenuse.
= sqrt((-8)^2 + 3^2) = sqrt(64+9) = sqrt(73)
Finally use trig ratios for cos, csc, and tan. (csc = 1/sin)
SOH --> sin = opp/hyp = 3/sqrt(73)
csc = 1/sin = sqrt(73)/3
CAH---> cos = adj/hyp = -8/sqrt(73) = (-8*sqrt(73))/73
TOA ---> tan = opp/adj = -3/8
Refer to the diagram below.
Let x = length of line segment RS.
Let Q = ∠RQS.
Let S = ∠RSQ
According to the Law of Sines,
Because the sum of angles in a triangle is 180°, therefore
∠Q = 180 -(80 + 49.68) = 50.32°
Apply the Law of Sines again to obtain
Answer: The length of RS = 2.4 (nearest tenth)
