Answer:
C. 95
Explanation:
Start by finding the two other angles in the triangle.
121* and 144* both have supplementary angles in the triangle. This means their counterparts added to them equals 180*
180-121=59 and 180-144=36
These are two of the angles in the triangle. Every triangle's angles add up to 180, so add the two together and then subtract that from 180.
180-(59+36)=180-95=85*
So the angle next to n is 85*. But, this angle and angle n are supplementary as well!
So, 180-85=n
n=95
There's probably other ways to solve this one, but this is how I'd do it. Hope I helped!
