The measure of two angles of a triangle are 67° and 43°. What ...
The sum of the measures of the angles in a triangle is always 180 degrees. Let's call the measure of the third angle x.

So we have:

67 + 67 + x = 180

Simplifying the equation:

134 + x = 180

Subtracting 134 from both sides:

x = 180 - 134

x = 46

Therefore, the measure of the third angle is 46 degrees.
