<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>.

A³b² a²b simplify the following expression
liberstina [14]

Answer:

a^{5}b^{3}

Step-by-step explanation:

The law of indices can be used to simplify mathematical expressions involving  arithmetical operation on variables with powers.

a^{m} x a^{n} = a^{(m+n)}

Thus, the given expression can be simplified as follows:

a³b² a²b  = a³ x a² x b² x b^{1}

               = a^{3+2} x b^{2+1}

               = a^{5}b^{3}

Thus,

a³b² a²b  = a^{5}b^{3}

Jules ran 2/3 miles. Miles ran 5/8 more than Jules. How many miles did Miles run?
kifflom [539]
2/3 is equivalent to 16/24
and 5/8 is equivalent to 15/24 miles
15/24+16/24= 31/24

31/24 simplifies to 1 6/24
Which simplifies down to 1 1/6

Miles ran 1 and 1/6 miles
