the measurement of one angle of a right triangle is 43 degrees what is the measurement of the third angle

The third angle is 47 degrees

Step-by-step explanation:

It says in the question that it is a "right triangle", so that means that there has to be one 90 degree angle (right angle). A triangle's angles always add up to 180 degrees so you can just add 90 and 43 and subtract the sum from 180:

180 - (43 + 90) = a

180 - 133 = a

47 = a

That means that the third angle is 47 degrees.
