The sum of the angles in a triangle is always 180 degrees. To find the third angle when the other two angles are given, you can use the formula:
\[
\text{Third angle} = 180 - (\text{First angle} + \text{Second angle})
\]
In your case, the two angles are 25 and 68:
\[
\text{Third angle} = 180 - (25 + 68)
\]
Calculating the sum of the first two angles:
\[
25 + 68 = 93
\]
Now, substitute that back into the equation:
\[
\text{Third angle} = 180 - 93 = 87
\]
So, the third angle measures **87 degrees**. The correct option is **87**.
\[
\text{Third angle} = 180 - (\text{First angle} + \text{Second angle})
\]
