Answer:
The customary system states that one pound is equivalent to sixteen ounces(oz).
Step-by-step explanation:
Since the package is one pound, it contains sixteen ounces(oz).
If BD is congruent to BC, that means that the sides are equal, so their angles are too.
6x-9 = 3x+24
3x = 33
x = 33/3
x = 11
Angle BCD:
6×11-9 = 66-9 =57°
Angle BDC:
3×11+24 = 33+24 = 57°
Angle B:
x = 180° - 2×57°
x = 66°
