Answer:
16 sides
Step-by-step explanation:
it's a regular polygon so all of it sides are equal
by that give, you should divide 12 by 3/4 and you will get 16
AC is b
15/tan55 = b
tan 55 = 1.428
15/1.428 = 10.5 cm = AC
If you mean 5 + 3 over 4, then:
5 + 3/4 = 5 3/4.
_________________________________
If you mean 5 + 3 divided by 4, then:
5 + 3 = 8
8 divided by 4 = 2.

x=-4
3x plus 4 =-8
3x=-8 -4
3x÷ -12 and you get -4
