Step-by-step explanation:
$1641.36
Remember that complementary angles add to 90 degrees.
so therefor, you can find the complement of m<A by solving
90 - 77 = A
A = 13 degrees
^^^ This explains the second part.
The compliment of a compliment can be found by subtracting the known compliment from 90 :)
When you factor you get (x-2)(x-3)=0 then x=2 and x=3
