Answer 1

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

Answer 2

35

Explanation:

n+90+55=180

n+145=180

n=180-145

n=35
