Answer:
All triangles add up to 180 degrees
right angles are 90 degrees
we add 41 and 90 to find how many degrees are already there
41 + 90 = 131
we need 180 degrees so we see how many degrees are left
180 - 131 = 49
49 degrees are left so 49 is the answer because 49 finishes the triangle

You take out the negative and do the regular equation but turn it into the fraction with one as the numerator and the solution of the exponent as the denominator.
