Can someone help me with this ? Thanks

Answer 1

it would be obtuse!.

Answer 2

Type of angle - Obtuse

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

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

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
