D) 54 degrees:
BD+AB+DE+2ACE" on the circumference twice on the center"=360
28+112+112+2ACE=360
2ACE=108
∠ACE=54
1.5 because you do -16=-8x-4
+4 +4
-------------------------------------------------------
-12=-8x
---------------------------------------------
- 8 -8
-12/-8 equals 1.5

Hello,
Let's assume f the age of the father,
s the age of the son.
<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)
</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)
(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40
</span>
