Answer:
x - 17.95 = 71.80, $89.75
Step-by-step explanation:
Let the original price of the headphones be x
Amount of coupon = $17.95
You pay the final amount for the headphones after using the coupon = $71.80
So to find the original price of the headphones, the equation will be
x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75
A) Using the special right triangle ratio for 30-60-90 triangles (which is 1-√3-2, opposite sides of the angles respectively, we can find that the side opposite the sixty degree angle is 41√3.
b) The hypotenuse is the same. Using the ratios, we see that the hypotenuse is 82.
c)sin(30)= opp/hyp = 41/82 = 1/2
cos(30)= adj/hyp = 41√3/82 = √3/2
tan(30)= opp/adj = 41/41√3 = 1/√3 = √3/3
