Find the sum of the angle measure of a hexagon

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

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

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?
