X = 32.
117 + 31 = 148.
180 - 148 = 32. (All angles in a triangle add up to 180 degrees)

Batman
Answer:
x = 3±√5
Step-by-step explanation:
x² - 6x + 4 = 0
x² - 6x + 9 = -4 + 9
(x - 3)² = 5
x - 3 = ±√5
x = 3±√5
X - 6y=18
2x-3y=9 |*-2
x -6y=18
-4x+6y=-18
----------------
-3x=0, x=0
2x-3y=9
2*0-3y=9
-3y=9, y=-9/3, y= -3
4 x 300 = 1200
0.58 x 90 = 52.2
1200 + 52.2 = 1252.2
