The answer is 4a - 12 so b.
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
c is the answer cuz a is a straight line of dots b is a no solution plot and d is a poitive plot
The number is -11/4 less than -8/3
Answer: 40:27
Step-by-step explanation: 80:54 / 2:2 = 40:27
