In an isosceles triangle ABC with AC = BC, point M is on the side BC , and point N is on the segment MC . It is known that MN=AM, and m∠BAM=m∠NAC. Find m∠MAC.

34

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
