The proof is correctly started by <u>both </u><u>Eric</u><u> and </u><u>Maggie</u>. Also, the next step in the proof is to <u>multiply both </u><u>sides</u> by the <u>denominator</u>.

<h3>What is the law of sines?</h3>

In Trigonometry, the law of sines is also referred to as sine law or sine rule and it refers to an equation that relates the side lengths of a triangle to the sines of its angles.

Mathematically, the law of sines is given by this equation:

\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}

From the given triangle, we can deduce that:

  • sin(X) = h₁/z   ⇒ h₁ = zsin(X).
  • sin(Z) = h₁/x   ⇒ h₁ = xsin(Z).
  • sin(Y) = h₂/x   ⇒ h₂ = xsin(Y).
  • sin(X) = h₂/y   ⇒ h₂ = ysin(X).

Therefore, the proof is correctly started by <u>both </u><u>Eric</u><u> and </u><u>Maggie</u>. Also, the next step in the proof is to <u>multiply both </u><u>sides</u> by the <u>denominator</u>.

Rick bought some tetra fish and goldfish for his fish tank. He bought twice as many goldfish as he did tetras. Each goldfish cos
kolezko [41]

The system of equations that can be used to determine the number of tetra fish and goldfish purchased is:
x = 2 y. 2 x + 1.5 y = 20

<h3>What are the system of equations ?</h3>

In order to determine the required values, two linear equations would be formed from the question. The two equations would exhibit the relationship between the two types of fishes:

The first equation would show the ratio between the two types of fishes bought: 2y = x

Th second equation would show the total cost of the two type of fish:1.5y + 2x = 20

A tin of biscuits contains shortbread and choc-chip biscuits in the ratio 2:3 . The tin contains 80 biscuits. How many short-bre
Aleksandr [31]

Answer:

32

Step-by-step explanation:

There are 80 biscuits inside the tin.

Also, they said that those biscuits are in the ratio

Short bread    :      Choc - chip

          2          :        3

Altogether there are 5 shares ( 2 + 3)

And now you can divide 80 by 5 to find how many biscuits contain per a share.

80 ÷ 5 = 16

In the question, they asked us to to find the number of short biscuits inside the tin.

Let us find that.

There are 2 shares for short bread biscuits.

So,

Number of short biscuits ⇒ 2 × 16

                                         ⇒ 32

Hope this helps you :-)
