if three angles are complementary, then they all ad up to 90 degrees. if the third angle is 10 degrees, then there are multiple answers for the other angles. one could be 35 degrees and 45 degrees.
So complementary angles add up to 90 Degrees. SO if 2 angles are the same and the third angle is 10. Then subtract 90-10 which is 80. Then divide it by 2 because 2 angles have the same length. 80/2 is 40. So the measurement of the other angles is 40 degrees.
If you're saying that the scale is 10 cm: 1 mm then the scale will be larger than the actual object because for every 1 mm of the object it will equal 10 cm of the scale drawing.
