What is the value of n
Crank

Answer:

The correct answer is option D. 69°

Step-by-step explanation:

Points to remember

1). The sum of angles in a linear pair is 180°

2). In a triangle sum of two angles are equal to the exterior angle of third angle

From the figure we can see a triangle in which two exterior angles area given.

<u>To find the value of n</u>

from figure we get,

n = (interior angle of 131°  + interior angle of 160°)

interior angle of 131° = 180 - 131 = 49°

interior angle of 160° = 180 - 160 = 20°

n =  49° + 20° =  69°

Therefore the  correct answer is option D. 69°
