Set the angles equal to 180
x + 2x + 3x = 180
6x = 180
Solve for x
6x = 180
x = 30
Plug that into angle C
2(30) = 60
Angle C is 60 degrees
1/2 as a decimal is 0.50
5/6 as a decimal is 0.83 continued so we know 5/6 will come after 1/2
0.83 is closer to 1 so it would be D.
) It bends light rays inward.
Flip the situation:
X + 3.25 = 4.72
Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25
X = 1.47
Ok what you have to do is you have to multiply 32x12 wich would equal = 54
