Explanation:
If ^A=70, then ^A=^B
Reason being ADııBC or Alternate Angles
if ^D=105,^C=105
Because ADııBC or Alternate Angles
if ^B=2x-6 and ^A=82 then...
x=2x-6=82
TRANSPOSE (remember that signs change)
2x=82+6
2x/2=88/2
x=44
if^C=2(y+4) and ^D=116 then...
^C=^D
2(y+4)=116
(2×y)+(2×4)=116
2y+8=116
TRANSPOSE
2y=116-8
2y/2=108/2
y=54
if ¯AC=56cm then ¯DB
¯AC=¯DB
because ADııBC
