Answer:
n = 21
Step-by-step explanation:
Given
n + 19 = 40 ( subtract 19 from both sides )
n = 40 - 19 = 21
X=60degrees
bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.
Hope this helps.
