For the the ode y" - 4y = 0, (a) verify if y_1 = cosh 2x, y_2 = sinh 2x form a fundamental set of the solutions of y" - 4y = 0: (b) form the general solution of the ode y" - 4y = 0.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
