In the right triangle ABC, CD is an altitude, and c=e+f, by combining three equations it can be shown that a^2+b^2=c^2.One of the equations is c=e+f. which of the following could be the other two equations

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
