Multiplication not to sure hope this helps :)
14-6=p
Or: 6+p=14
One of those should work :)
The answer is 8.
Let me know if you still need help.
Two complementary angles must add to 90 degrees, and if you divide 90 into thirds (two parts for the larger angle, one for the smaller), then you get 30 degrees.
If the smaller angle is 30 degrees, then the larger is two times that, which is 60. 60 + 30 = 90, so the larger angle is equal to 60 degrees.
