Answer:
35
Step-by-step explanation:
n+90+55=180
n+145=180
n=180-145
n=35
Answer: n = 35 degrees
Step-by-step explanation: You have been given the measures of two angles: 55 degrees and 90 degrees. To solve for n, simply add them and subtract that sum from 180.
Equation and Solution:
n = 180 - (55 + 90) degrees
n = 180 - 145 degrees
n = 35 degrees
