What is the value of n?
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
