Answer:
x = 8°, y = 28°
Angles are 64° and 116°
Explanation:
Parallelogram
Opposite angles of a parallelogram are congruent, that is, they have the same measure, thus:
4y = y + 87
8x = 7x + 8
These are two separate equations that can be solved independently.
Subtracting y to the first equation:
3y = 87
Dividing by 3:
y = 87/3 = 29
y = 29°
Subtracting 7x to the second equation:
x = 8°
The internal angles of the parallelogram are:
8x = 64°
4y = 116°
The question doesn't have any specific requirements, so I solved the variables and calculated the angles.
