Answer:
both angles are = to 59º
Explanation:
remember that alternate exterior angles are equal to each other. if one angle is x than the other angle is also x!
so in this case, (6x+5) = (7x-4) <--- remember both exterior angles are same!
so solve for x now.
6x + 5 = 7x - 4
5 = x -4
9 = x
now put it back into one of the expressions
6(9) + 5 = ?
54 + 5 = 59º
