Question

i dont need the answer, i just need an explanation of how to do right angles. like is it the same as 180? u just subtract the other numbers ?

Answer 1

Yes to find the angles of the triangle, it has to equal 180 degrees. Since one of the angles is already a right angle its 90 degrees plus the 57 degree angle it equals 147 degrees. 180-147 = 33 degrees.
