Answer:
Missing angle = 76 degrees
Informal Argument found below
Step-by-step explanation:
In order to find the missing angle, we would need to add up all of the known angles and subtract them from 180. This is because in every triangle, the angles add up to 180.
Work:
180 = 79 + 25 + x
180 = 104 + x
x = 76
Informal Argument:
The missing angle of the triangle is equal to 76 degrees. This is because all of the angles in a triangle always add up to 180 degrees. When combined with the other two angles, the triangle has a total angle measurement of 180 degrees. Therefore, the missing angle is equal to 76 degrees.
