Answer:
Infinite Solutions
Step-by-step explanation:
x + y = 4
y = -x + 4
x + y = 4
x - x + 4 = 4
0 = 0
Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43
