- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
∅ = 40°
opposite leg of angle = 50 ft
hypotenuse = x ft
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin40° = 50/x
- Multiply <em>x </em>on both sides: xsin40° = 50
- Divide sin40° on both sides: x = 50/sin40°
- Evaluate: x = 77.7862
- Round: x = 77.8 ft
The answer is -37! You would substitute the numbers you were given for the variables so the equation would become 5(3) -3 + 7(-7)
Answer:
F- the first answer choice
Step-by-step explanation:
The amount of stone in each sidewalk is 3/16
<h3>How to determine the amount of stone in each sidewalk?</h3>
The given parameters are
Stones = 3/4 tons
Side walks = 4
The amount of stone in each sidewalk is calculated using
Amount = Stones/Side walks
Substitute the known values in the above equation
Amount = 3/4 / 4
Evaluate the quotient
Amount = 3/16
Hence, the amount of stone in each sidewalk is 3/16
