First we find the angle measures of the adjacent angles:

180 - 144 = 36

180 - 121 = 59

Now we find the third angle inside of the triangle

180 - (36 + 59) = 85

<n and 85 are supplementary so we subtract by 180

180 - 85 = 95

<n = 95

Answer:

95

Step-by-step explanation:

We are given a triangle with two exterior angles as 120 and 144

We have to find the third exterior angle.

We know that in any polygon (closed figure formed by straight lines) the sum of exterior angles would be 360 degrees

Hence here applying the same principle as above we get

121+144+angle n = 360

265+n=360

Subtract 265 from both the sides

We get

n =95

Answer is angle n = 95
