The output voltage (V) from a power supply circuit if given by v = -21 +25 volts, where I is current. The circuit is operated between the limits of 0.1A and 0.6A. Using integration determine the mean
value of the output voltage.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
