Answer:
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
