Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.
Complementary angles are angles that add up to 90 degrees. So, the complementary angle of 70 degrees would be 20 degrees
2x-10+3x-10=90 5x-20=90 5x=110 x=22
first you have to change this into equation by "translating" it into math. so let x= the first angle 90-x ( because complementary means they add up to 90) = the second angle x= (90-x) + 20 x+x = 90-x+20+x 2x = 90-20 2x = 70 x = 35 the smaller angle = 35 degrees
The angle is 160 degrees and it's supplement is 20 degrees.
