Exterior angle theorem

Answer:
n = 29 , k = 6
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
5n + 3 = 90 + 58
5n + 3 = 148 ( subtract 3 from both sides )
5n = 145 ( divide both sides by 5 )
n = 29
---------------------------------------------------
5k + 4 + 90 = 124
5k + 94 = 124 ( subtract 94 from both sides )
5k = 30 ( divide both sides by 5 )
k = 6
