the internal angles in a triangle addd to 180

so if 2 of them add to 86 then the 3rd must be x
86+x=180
minus 86 both sides
x=94
the 3rd angle must be 94°

Answer:

94 degrees

Step-by-step explanation:

The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.
