Answer: A) 2/3

Method: Here’s an easy method for questions like these, when you are looking at a triangle, look at the angle that’s away from the biggest line (if it’s a right triangle choose any angle), for this case angle W. Now count how many lines it takes to get to the big line, for the original triangle it’s 6 and for the new triangle it’s 4. Now since you have your numbers turn it into a fraction (new on top original on bottom), 4/6. Finally see what the answer is, for this case 4/6 is equal to 2/3, so there’s your answer.

Nina [5.8K]

Answer:

The rounded number is 10,000.

Step-by-step explanation:

Rounding means making a number simpler but keeping its value close to what it was.

The digit in the ten thousands place is 1.

The digit to its right is 2, so the digit in the ten thousands place stays the same.

Leave it the same if the next digit is less than 5, this is called rounding down. And increase it by 1 if the next digit is 5 or more, this is called rounding up
