A right angle has one angle that measure 40. What is the measure of the other acute angle

The other acute angle is 50 degrees.

Step-by-step explanation:

In order to find this, we need to know two things. Firstly, that a right triangle has a 90 degree angle. Secondly, that all triangles have 180 degrees of angle on the inside. So, to solve for the final angle, we can add the other two and x to get 180.

90 + 40 + x = 180

130 + x = 180

x = 50
