Answer:
To find the measure of the third angle in a triangle, we can use the fact that the sum of the three angles in a triangle is always 180°.
Let's denote the measure of the third angle as x. So, we have the equation:
14° + 23° + x = 180°.
Combining like terms, we have:
37° + x = 180°.
Subtracting 37° from both sides of the equation, we get:
x = 180° - 37°.
Simplifying, we find:
x = 143°.
Therefore, the measure of the third angle in the triangle is 143°.
