Answer:
The answer is 60 degrees.
Step-by-step explanation:
The three angles in any triangle add up to 180 degrees.
You know by the box at the bottom right that it's a right triangle and therefore that angle is 90 degrees. They also give you the 30 degree angle at the bottom left. So:
90 degrees + 30 degrees = 120 degrees.
180 degrees (total) - 120 degrees (first 2 angles) = 60 degrees (missing angle)

Answer:
x = 67.5
Step-by-step explanation:
If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.
AB is parallel to NP and intersects the other 2 sides , then
= 
( substitute values )
= 
, that is
= ( cross- multiply )
49.5(97.5 - x) = 22x ← distribute left side
4826.25 - 49.5x = 22x ( add 49.5x to both sides )
4826.25 = 71.5x ( divide both sides by 71.5 )
67.5 = x
