Use the Law of Sines to find the measure of angle R to the nearest degree.
IrinaK [193]
\frac{\sin(R)}{PQ} = \frac{\sin(Q)}{PR}

\frac{\sin(R)}{24.7} = \frac{\sin(43^{\circ})}{16.9}

\sin(R) = 24.7*\frac{\sin(43^{\circ})}{16.9}

\sin(R) \approx 0.9967668

R \approx \arcsin(0.9967668)

R \approx 85.39137896^{\circ}

R \approx 85^{\circ}

The final answer is 85 degrees

For a given input value x, the function h outputs a value y to satisfy the following equation 6x+y=4x+11y. Write a formula for h
Tanzania [10]

Answer: h(x) = \frac{1}{5}x

<u>Step-by-step explanation:</u>

6x + y = 4x + 11y

<u>      -y </u>    <u>        -y  </u>

6x       = 4x + 10y

<u>-4x   </u>      <u>-4x         </u>

2x       =         10y

<u>÷10    </u>     <u>       ÷10 </u>

\frac{1}{5}x    =            y

Since "y" represents h(x), then h(x) = \frac{1}{5}x

The factored form of the given expressions are

y = (x -2)(x +7)

y = (x +6)(x -9)

y = (x +2)(x +6)

y = (x -5)(x -6)

y = (x +5)(x -5)

y = (x -1)(x +9)

y = (x +4)(x -4)

<h3>Factoring quadratic expressions</h3>

From the question we are to factor the given quadratic expressions

  • y = x² + 5x - 14

y = x² +7x -2x - 14

y = x(x +7) -2(x +7)

y = (x -2)(x +7)

  • y = x² -3x - 54

y = x² -9x +6x - 54

y = x(x -9) +6(x -9)

y = (x +6)(x -9)

  • y = x² +8x + 12

y = x² +6x +2x +12

y = x(x +6) +2(x +6)

y = (x +2)(x +6)

  • y = x² -11x +30

y = x² -6x -5x +30

y = x(x -6) -5(x -6)

y = (x -5)(x -6)

  • y = x² - 25

y = (x +5)(x -5)

  • y = x² + 8x - 9

y = x² +9x -x -9

y = x(x +9) -1(x +9)

y = (x -1)(x +9)

  • y = x² - 16

y = (x +4)(x -4)

Hence, the factored form of the given expressions are

y = (x -2)(x +7)

y = (x +6)(x -9)

y = (x +2)(x +6)

y = (x -5)(x -6)

y = (x +5)(x -5)

y = (x -1)(x +9)

y = (x +4)(x -4)
