Someonewhat is the value of n? ?

Remark

External angles added to an internal angle = 180o

Every triangle has 180 degrees.

Step One

Find the supplement of 131: Call the Supplement x

x + 131 = 180

x = 180 - 131

x = 49

Step Two

Find the supplement of 160o. Call that angle y

y + 160 = 180

y = 20

step 3

Find the value of the supplement to n. Remember every triangle has 180 degrees. Call this angle z

x + y + z = 180 degrees

49 + 20 + z = 180

69 + z = 180

z = 180 - 69

z = 111

Step Four

Find the supplement to z (which is n)

z + n = 180

111 + n = 180

n = 180 - 111

n = 69
