Answer:

  (b) 15.32

Step-by-step explanation:

You can use your triangle sense to answer this.

The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.

If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.

__

The mnemonic SOH CAH TOA reminds you of the relation ...

  Sin = Opposite/Hypotenuse

  sin(50°) = x/20

  x = 20×sin(50°) . . . . multiply by 20 to find x

  x ≈ 15.32 . . . . . . . . . use your calculator to evaluate

__

The attachment is intended to show how the triangle side lengths change with angle.

Two golfers completed one round of golf. The first golfer had a score of +6 and the second golfer had a score of –3. How many mo
Monica [59]

                                             Question 16

Given that two golfers completed one round of golf.

It is stated that the first golfer had a score of +6 and the second golfer had a score of -3.

  • Let suppose 'x' be the number of shots the first golfer took.

It is clear that the first golfer is 6 over par, while the second golfer is under 3.

Thus, the equation becomes:

-3 + x = 6

adding -3 to both sides

-3+3+x = 6+3

simplify

x = 9

Thus, the second golfer has taken 9 more shorts.

                                             Question 17

When we talk about credit, it means:

Credit = +

When we talk about debt, it means:

Debit = -

Thus,

Credit = +84

Debt = -29

Balance = 84 + (-29)

              = 84 - 29

               = 55

Thus, the balance is: 55

How does a digit in the ten thousand place compare to a digit in the thousands place
Butoxors [25]
A digit in the ten thousand place has a value of 10,000 times the value of the mere digit. While a digit in the thousands place has a value 1,000 times the value of the digit. So to compare you can do 10,000 / 1,000 = 10, which means that<span> a digit in the ten thousand place values ten times what the same digit values is it is the thousand place. </span>
