Answer:
x=1/4 y=1/4
Step-by-step explanation:
They mean x-coordinate and y-coordinate
IN A triangle, sum of all angles = 180 degrees
2x + 3 + 4x+2 + 2x -1 = 180
8x +4 = 180
8x = 176
x = 176 /8 = 22 degrees
the angles are A = 2(22)+3 = 44+3 = 47 DEGREES
B = 4(22)+2 = 88 + 2 = 90 DEGREES
C = 2(22) -1 44-1 = 43 DEGREES
The correct answer is 31. I did it incorrectly the first time, but the answer is 31. :-) Thanks Olivia!
