a = 3, b = 4, and c = 5. Using the Law of Cosines, find all angles in the triangle.
a. A = 90ø, B = 45ø, and C = 53ø
b. A = 53.13ø, B = 90ø, C = 36.87ø
c. A = 45ø, B = 45ø, C = 36.87ø
d. A = 36.87ø, B = 53.13ø, C = 90ø
e. A = 60ø, B = 60ø, C = 60ø
d. A = 36.87ø, B = 53.13ø, C = 90ø

Solve the problem.A simple electrical circuit consists of a resistor connected between the terminals of a battery. The voltage V (in volts) is dropping as the battery wears out. At the same time, the resistance R (in ohms) is increasing as the resistor heats up. The power P (in watts) dissipated by the circuit is given by P = src="https://sciemce.com/media/4/ppg__wra0609191916__f1q193g5.jpg" style="vertical-align: -17.0px;" />
