Answer:
the answer would be 217 [degrees]
Step-by-step explanation:
Since m<1 and m<2 are next to each other, they are adjacent. Adjacent angles must share a common side which is m<W. This means they have to be added. m<1+m<2= m<XYZ
145+72=217
I hope this will help u <span>It looks like 12 is the smallest number that can be divided by both 3 and 4, so 12 is our LCD. Since 12 is the LCD, it will be the new denominator for our fractions. Now we'll change the </span>numerators<span> of the fractions, just like we changed the denominators. First, let's look at the fraction on the left: 1/4.</span>
If it is 50 pages in an hour, half an hour would be 25 pages, and if it is 40 pages in an hour it would be 20 pages in half an hour, the answer is 5 pages more in half hour
