Answer:
-191
Step-by-step explanation:
Replace variables with corresponding value.
3(3) + (-5)^2 - ((3)(-5))^2
Solve exponent.
3(3) + 25 - 225
Multiply.
9 + 25 - 225
Combine like terms.

Answer:
27
Step-by-step explanation:
Use exponent laws
1/3^-3 = 3^3 = 27
The law of cosines states that:
c^2=a^2+b^2-2abcosC
You already have all the values for the variables with the exception of x so:
x^2=25+100-100cos60
x=√(125-100cos60)
x=√75
x≈8.66 to nearest one-hundredth...
