To find the third angle of a triangle, we can use the Triangle Angle Sum Theorem which states that the sum of the three angles in a triangle is always 180 degrees.
Let's say the third angle is represented by x.
According to the problem, the first angle measures 25 degrees and the second angle measures 68 degrees.
To find the third angle, we can set up the equation:
25 + 68 + x = 180
Combining like terms, we have:
93 + x = 180
Subtracting 93 from both sides, we get:
x = 180 - 93
x = 87
Therefore, the third angle measures 87 degrees.
Answer: 87
use the triangle angle sum theorem to find the third angle of a triangle if the other two angles measure 25 and 68
