How to find the missing side of a triangle in trig for geometry

Mathematics
1 answer:
dsp732 years ago
8 0

Step-by-step explanation:

cosine is cos(angle)= adjacent/hypotenuse

sine is sin(angle) = opposite/hypotenuse

Tangent is tan(angle)= opposite/adjacent

for all of those

if the equation is something like tan(69)= x/69

multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator

if it is something like tan(69)= 69/x

just swap x and tan(69)

it is much easier

it will then be 69/tan(69) and put that in the calculator

Finger [1]

Answer:

  D.  $66.23

Step-by-step explanation:

The sale discounts your purchase by half the price of a pair of pants, so you pay for 2.5 pairs of pants. The sale price of the pants is then ...

  $24.99 × 2.5 = $62.48

The added tax multiplies this value by 1.06, so you pay ...

  1.06 × $62.48 = $66.23

_____

<em>Comment on the answer</em>

Whether you pay $66.23 or $66.22 depends on how the discount is calculated. If you get the benefit of the half-penny (the discount is rounded up), then the sale price is $62.47 and the total is $66.22.
