6/10 - 1/2...common denominator is 10
6/10 - 5/10 = 1/10 <==
Use the identity: 
and solve for 
. You get: 
Do the substitution on the left side to get:
Answer:
x = 34°
Step-by-step explanation:
To solve for 'x', we will need to use the Supplementary Angles theorem. This states that on a line, all angles must add up to 180°.
We can set up a simple algebraic equation to solve for 'x':
180 = x + 12 + 100 + x
180 = 112 + 2x **Combine like terms
68 = 2x **Divide both sides by '2'
x = 34°.
Therefore, the measure of ∠x = 34°.
N/10 = 32,7
N = 32,7*10
N = 327
