Hello!
If the signs are the same, and you multiply or divide, the sign of the product or quotient will be positive. If the signs are different, the product or quotient will be negative.
Answer and Step-by-step explanation: The described right triangle is in the attachment.
As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:
AC² = AB² + BC²
AB = 5.4
Then, right triangle ABC measures:
AB = 5.4cm
BC = 4.5cm
AC = 7cm
60 * 0.10 = 6
