Answer:
Multiplication
Step-by-step explanation:
Follow GEMDAS or PEMDAS. I would recommend GEMDAS. GEMDAS stands for Grouping symbols, exponents, multiply, divide, addition, subtraction. GO form the order G to S
Step 1) Add up the three given angles: 125+109+83 = 317
Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43
The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.
The answer is 43
Answer:
500 mL
Step-by-step explanation:
1 L = 1,000 mL
-> We use the formula of L * 1,000 = mL
1,000 mL / 2 = 500 mL
-> We only have half of the L, so we can divide it by 2 to get the correct number of mL
Have a nice day!
