Which expression is equivalent to the following complex fraction? \frac{\frac{-5}{2}}{\frac{3}{8}}

m∠vru = 80°

m∠urw = 15°

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
