    No need for trig ratios, use the Pythagorean theorem

    c=\sqrt{a^2+b^2}

    Ok, draw your triangle, and then use the fact that for an angle theta

    \theta=\arcsin\bigg(\frac{o}{h}\bigg)

    and so forth...are you aware of this method?

    And you still need to find the hypotenuse

    c=\sqrt{9.3^2+7.5^2}\approx{11.95}
