Answer:
10%
Step-by-step explanation:
$179.99+$20=$199.99
$20/$199.99=0.1000
=10%
Not sure why they put the x bit
ok so know this:
AGE=HGB=CHG=FHD
and
AGH=EGB=CHF=GHD
and
AGE+AGH=180
11.
AGE=FHD=30
12.
AGH=CHF=150
13.
CHF=BGE=110
14.
CHG+HGA=180
CHG+120=180
CHG=60
15.
BHG=3x=AGE=CHG=FHD
not sure, but if we did use the fact that BGH+DHG=180 and BGH=3x and DHG=2x+50 then BHG=78 degrees
16.
GHD=2x+50=CHF=EGB=AGH, if we use facts above then GHD=102 degrees
answer 22
beqause parallelograms are 180 ° = A + B = 90 ° AND AND C + D = 90° AND B = C , A= D then
A + B = 90° A= 68 THEN 68 + B = 90° = B = 90 ° - 68 ° = 22°
