180 degrees minus 74 degrees 51 minutes
105 degrees 9 minutes
180(degrees) - x
Supplementary angles are angles adjacent to each other whose sum adds up to 180 degrees.
So you can set up the equation:
supplement of x + x = 180
The answer to the question requires solving for the supplement of x:
supplement of x = 180 - x (This is your answer)
therefore the sum of our angles will be:
solving for x we get:
hence the value of the supplement of 70° is 80°
To find a supplement, you take the measure of the angle you know and subtract that from 180. So 180-164=16.
Hope this helps! :D
