Question

The measure of L in triangle LMN is 32°. The measure of M is 69°. What is the measure of N?
A.
79°
B.
259°
C.
101°
D.
37°

Answer 1

Answer:

A) 79

Step-by-step explanation:

m<N = x

All angles in a triangle add up to 180 so:

x + m<L + m<M = 180

x + 32 + 69 = 180

x + 101 = 180

x = 180 - 101

x = 79

Answer 2

Answer:

It is (A) 79°

The summation of the triangle's angles are 180°

Step-by-step explanation:

$m + l + n = 180 \\ 69 + 32 + n = 180 \\ n = 180 - 101 \\ n = 79 ^{ {} ^{.} }$
