Answer:
294.71
Step-by-step explanation:
298.8-4.09=294.71
The angle 53° is half the difference of the intercepted arcs, so is
53 = (180 - y)/2
106 = 180 - y
y = 180 - 106 = 74
-4/3x + 1/6 < 7/9
-4/3x < 7/9 - 1/6 7/9 - 1/6 = 42/54 - 9/54 = 33/54 = 11/18
-4/3x < 11/18
-x < 11/18 ÷ 4/3 11/18 ÷ 4/3 = 11/24
-x < 11/24
x > -11/24
