The angle required will be given by:
x=52/5π-5*2π=2/5π
the positive angle less than one revolution around the unit circle that os co-terminal with angle of 52/5π is 2/5π
-3/11
Step-by-step explanation:
7-10/3-(-8)
7-10/3+8
Both triangles that are given (with right angles) lie in plane m, proving that AC is perpendicular to plane m. As angle acd is from a triangle that shares the common perpendicular, it too is a right angle

The sign at the end changes because both sides of the equation are being divided by a negative number.
