The answer would be E. because if the determining number (The number directly after the place being rounded to. The 8 in this case) is greater than five, you round up and drop the numbers after the place being rounded to (The hundredth's place), if it's less, the number in the place being rounded to stays the same, but you still drop the numbers after it.
Answer:
The measure of the largest angle is 72º.
Step-by-step explanation:
We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.
You take 3•4 to get 12, then you add a zero to that and get 120. You then multiply by six and get 720.
