Due to the lengths a and b being equal, their angles will also be equal, having a value of 45° each.
Thus, sin(A) = sin(B)
The third option is correct.

What does it mean when the ratio of person 1’s income to person 2’s incomes is 1 to 3 or 3 to 1? Explain.
viktelen [127]

Tameka built 1/2 of a shed on Monday and 2/5 of the shed on Tuesday. Tameka finished building the shed of Wednesday. What fracti
Doss [256]

Step One

Find the sum of the fractions for Monday and Tuesday

1/2 + 2/5

The common denominator for these 2 days is 10

1/2: 1*5/(2*5) = 5/10

2/5:2*2/(2*5) = 4/10

Add these two equivalent fractions together.

5/10 + 4/10 = 9/10

The first 2 days resulted in 9/10 of the shed being completed.

Step Two

Find out how much (in terms of fractions) is left of the shed.

Let the whole shed = 1

Let what has been done = 9/10

What remains is 1 - 9/10 = 1/10

Answer: 1/10 of the shed needs to be done

Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the
hammer [34]

Answer:

\frac{1}{4}

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = P_{1}=\frac{13}{52}

After replacement, the probability of second card is heart = P_{2}=\frac{13}{52}

after replacement, the probability of third card is heart =  P_{3}=\frac{13}{52}

P =  \frac{13}{52} ×  \frac{13}{52} ×  \frac{13}{52}

  =  \frac{39}{156}

  =  \frac{1}{4}

The probability of all three cards are hearts is  \frac{1}{4}
