The work become much simpler if you do it in a table. Hope this helps!!
We know that two complements add up to 90.
Let's call the smaller angle x and the larger y.
3x = y
x + y = 90
We can use simple substitution.
x + 3x = 90
4x = 90
x = 22.5
Then, since we know that 3x=y, we can find the larger angle.
3*22.5 = 67.5
60 points! Because 8 questions wrong would be - 40 points and its out of 100 points so 60 points
