In angles 31' means 31 minutes. And one degree is equal to 60 minutes, then 31' is 31/60 ° = 0.51667 °

That measure is too small if you use it you will obtain this result:

x = 500 ft * tan (31/60°) = 4.51 ft which is too little.

I will answer the problem using 31° instead of 31'.

This is answer and full explanation:

Answer: 300 ft.

Explanation:

You can form a right triangle with these features:

1) Base = adjacent-leg = 500 feet

2) angle between the hypotenuse and the base = 31°

3) Height = opposite-leg = height of the Statue of LIberty = x

Now, use the equation for the trigonometric ratio tangent:

tan(angle) = opposite-leg / adjacent-leg

=> tan (31°) = x / 500ft

=> x = 500ft * tan(31°)

x = 300.43 ft which rounded to the nearest foot is 300 ft.

Anyone by chance know how to answer this geometry question I need help so bad
NemiM [27]

Answer:

x = -8 and BDC is 68 degrees.

Step-by-step explanation:

Combine -7x+12 and -8x+48 to get -15x+60.  Since BDA is a straight angle put the above equation to get -15x+60=180.  Subtract 60 from both sides to get -15x=120.  Divide -15 both sides to get -8 as your x value.  Plug in -8 to BDC, since both negatives are being multiplied, it would turn to a positive number which is 56, add 12 to get 68 as your final result for BDC.

Nadya [2.5K]
0.0239 x 28 = .6692 (this is the amount of tax paid)
shoes + tax = total
$28 + 0.6692 = $28.6692 which rounds to $28.67 (money is always rounded to the hundredths place)
