Please try to follow me, as I demonstrate a method of solution.
This could get complicated. I'll try to go slowly, and you must
stop me if I do anything that's not clear.
Ready ?
You said that -5c/8 = 20
Multiply each side by 8: -5c = 160
Divide each side by 5 : - c = 32
Multiply each side by -1 : c = -32
Answer:
AD = 44 and angle CAB = 90 degrees
Step-by-step explanation:
since the shape is a rectangle, all corner angles must be 90 degrees. so CAB is also 90 degrees.
the length of half of BC is 22, so the full length of BC is 44. using symmetry, AD should also be 44.

The answer is B) 30
parenthesis first (5×-3)(-2)
5×-3= -15
-15×-2= 30
