Pick any two pairs of equations<span> from the system. Eliminate the same </span>variable<span> from each pair using the Addition/Subtraction method. Solve the system of the two new </span>equations<span> using the Addition/Subtraction method.</span>
In your graphing calculator, you can press 2nd then cos to create cos^-1 and then press 0.5967.
You’re basically doing arccos(0.5967) or cos^-1(0.5967)
Remember to put your calculator into radian mode first.
Your answer will be 0.9314138684 in radian
For degrees it would be 53.36608364
Base = 5 * 12 = 60 in^2
Height = 4 in
Perimeter is the sum of all straight
Perimeter = 20 + 16 + 48
Perimeter = 84 in
Perimeter of base = 12 * 2 + 5 * 2 = 34
