Question

if in a triangle angle M =55°,angle N=45°,find angle o​

Answer 1

Answer:

Step-by-step explanation:

we know that sum of angle of triangle is 180

∠m + ∠n + ∠o = 180

55 + 45 + ∠o = 180

∠o = 180 -100

∠o = 80

Answer 2

angle M + angle N + angle O = 180°

45°+55°+O=180°

100+O=180°

O=180-100

O=80
