Explanation:

Working off what the person below did, one way to figure it out is by taking the lines (A straight line is 180*)

So to figure it out you have the 121*, and that little segment next to it.

So 180*-121*= 59*. And since that little segment/corner is a vertical angle, You move the 59* Into the little corner in the triangle.

Same with 144*, it has a little segment next to it.

So 180*-144*=36*. Move that in.

A triangle is 180* on the inside. So 180*-36*-59*=85*. That is the last corner INSIDE the triangle.

Move that OUT.

it's in the little segment/corner next to n and it's on a line, So 180*-85*=95*

n=95*.

Answer:

The answer to your question is: n = 95°

Explanation:

The sum of the suplementary angles equals 180°

Then

121 + x = 180

x = 180 - 121

x = 59°

144 + y = 180

y = 180 - 144

y = 36°

The sum of the internal angles in a triangle equals 180°

x + y + z = 180

59 + 36 + z = 180

z = 180 - 59 - 36

z = 85

Finally

n + 85 = 180

n = 180 - 85

n = 95°
