The average of the 3 grades = (81+85+95) /3
=87
This counts as 2/3
of the final grade:
87 * 2/3 = 58 points
For a grade of 90, they still need 90 -58 = 32 points
Let x = final exam score
The final exam is worth 1/3, so we get:
1/3x = 32
To get x, multiply both sides by 3:
x = 32 *3
x = 96
They need a 96 on the final exam.

<span>Let @ = theta.
sin @ = sqrt(3) / 2
The sine function equals sqrt(3) / 2 at the following angles measured in degrees:
....,-300, 60, 420, 780,1140,....,60 + 360k and
....,-240, 120, 480, 840, 1200,....,120 + 360k where k is an integer.
@ = 60 + 360K and
@ = 120 + 360K
if k = 0 ; </span>@ = 60 degrees ;<span>
