  • Q11

    Using the law of cosine, which formula is to be used to find angle B?)

    b² = a² + c² - 2ac cos B

    b² = a² + c² + 2bc  cos B

    b² = a² + c² + 2ac  cos B

    b² = a² +  c² - 2bc cos B

    The measurements of two sides and  non-included  angle.

    The measurements of all three sides. 

    The measurements of all three angles.

    The measurements of two angles

  • Q14

    What is the formula for law of sines?

    \frac{a}{\sin\ A}=\frac{b}{\sin\ B}=\frac{c}{\sin\ C}

    \frac{a}{\sin\ B}=\frac{b}{\sin\ C}=\frac{c}{\sin\ A}

    \frac{A}{\sin\ a}=\frac{B}{\sin\ b}=\frac{C}{\sin\ c}

    \frac{\sin\ a}{a}=\frac{\sin\ b}{b}=\frac{\sin\ c}{c}
