The equation should be g/12 = 1/4. Since the sub was cut into 12 parts, then the total would have been divided by 12 to get 1/4 equal parts. To solve the equation you multiply 12 by 1/4. This will get you 3. This means the original sub was 3 feet long.
Answer:
y=60°
x=12°
Step-by-step explanation:
because the propertiy of parallelogram is the opposite side have equal measurement.
that is why y=60°
x+3=15 the paralla side are equal
x=15°-3°
x=12°
proof》》》》x+3=
12°+3°=15°
15°=15°
