Answer 1

It would be obtuse!.

Answer 2

Answer:

Type of angle - Obtuse

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

Equation - $(5y+12)=98$ $y=17.2$

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°

$(5y+12)=98$

$(5y-12)$  = -12          subtract 12 from both sides

$(5y)$           =  86        Now solve for y by dividing 86 ÷ 5

y = 17.2
