Can someone help me with this ? Thanks

Type of angle - Obtuse

Key information - 180° - 82° = 98° (missing angle)

Equation -

Step-by-step explanation:

Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.

then use the statement to solve for y and make it equal to 98°

 = -12          subtract 12 from both sides

          =  86        Now solve for y by dividing 86 ÷ 5

y = 17.2
