To find the missing angle in a triangle, we need to know the sum of the angles in a triangle, which is always 180 degrees.

Let's assume the missing angle is represented by x.

Given that two angles are 15 degrees and 85 degrees, we can write the equation:

15 + 85 + x = 180

Combining like terms:

100 + x = 180

Now, we can solve for x:

x = 180 - 100
x = 80

Therefore, the missing angle is 80 degrees.
