There are 180° in the sum of the angles of one side of a straight line.
The center angle is a right angle (the little box in its corner indicates a right angle), so it contains 90°.
This means that there are 90° left for the two angles of 3x + 10° and x + 20°.
An appropriate equation is: (3x + 10°) + (x + 20°) = 90°.

If you use the trig identity: sin(A + B) = sin(A)cos(B) + cos(A)sin(B):
Substituting A with x and B with 30:
---> 2[ sin(x + 30) ] = 2[ sin(x)cos(30) + cos(x)sin(30) ]
Since sin(30) = 1/2 and cos(30) = √(3)/2
---> 2[ sin(x)·√(3)/2 + cos(x)·(1/2) ]
Using the distributive property with 2:
---> √(3)sin(x) + cos(x)
To calculate a percentage, divide the part by the whole and multiply that answer by 100.

When multiplying fractions, multiply the numerator times the numerator and the denominator times the denominator.
(2/15) x (-5/8) = (2 x -5)/(15 x 8) = -10/120 = -1/12
The square root of -1 does not convert into a regular whole number, common fraction or decimal fraction.
