Answer:
Option 3
Step-by-step explanation:
This may not be the most efficient way, but I solved each one and option 3 had the same answer as the question.
Answer:
1. y = 14.718
2. ??
3. y = 39.794°
Step-by-step explanation:
<em>HINT the side we already know and the side we are trying to find, we use the first letters of their names and the phrase "SOHCAHTOA" to decide which function:
</em>
SOH...
Sine: sin(θ) = Opposite / Hypotenuse
...CAH...
Cosine: cos(θ) = Adjacent / Hypotenuse
...TOA
Tangent: tan(θ) = Opposite / Adjacent
1. Sine: sin(θ) = Opposite / Hypotenuse
sin(42°) = y / 22
so on your calculator enter 42 then sin = 0.669
0.669 = y/22 multiply both sides by 22 to get y
y = 14.718
2. is there any other information??
3. The two sides we know are Opposite 40 and Adjacent 48.
SOHCAHTOA tells us we must use Tangent.
Calculate Opposite/Adjacent = 40/48 = 0.833
Find the angle from your calculator using tan-1
Tan y° = opposite/adjacent = 40/48 = 0.833
tan-1 of 0.833 = 39.794°
The total cost of the customers order is s/2 + 1.50 dollars.
<u>Explanation:</u>
Let s represent the cost of sandwich
Cost of pretzels = 1.50 dollars
Special offer by deli lunch = Half of the cost of sandwich + bag of pretxel
Cost of offer. = s/2 + 1.50 dollars
Original order = 1 sandwich
Originial cost = s dollars
