Final answer:
To find the measurement of the missing angle in a triangle, subtract the sum of the given angles from 180 degrees.
Step-by-step explanation:
In a triangle, the sum of the measures of the three angles is always 180 degrees. So, to find the measurement of the missing angle, we subtract the sum of the given angles from 180 degrees.
Let x be the measurement of the missing angle.
65 + 45 + x = 180
x = 180 - 65 - 45 = 70
Therefore, the measurement of the missing angle in the triangle is 70 degrees.
