Question

Mathematics: Two straight lines intersect at a point to form angle a. The measure of the angle opposite to angle a is 30 degrees. Angle a is the angle of a right triangle having another angle equal to b. A triangle with one angle labeled c is on the left of the figure. The angle adjacent to c is labeled 75 degrees.

complex roots (zeros) occur in conjugate pairs __ if 7+4i is a zero, then 7-4i is also a zero

for the coefficients to be rational; any irrational zeros (sqrt(7)) must have a conjugate, so -sqrt(7) is also a zero

Two straight lines intersect at a point to form angle a. The measure of the angle
