Y=mx+b
m= slope so slope= .5
b= y intercept so y intercept=0
E. Commutative property of multiplication
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 :)
Sorry, my answer was wrong. I can't delete it so as not confuse anybody i changed it to this.
