Someone explain how to do this please!! dont need just an answer but explain as well
Leya [2.2K]

6.5 goes in the first box and 5.5 goes in the second box.

Explanation for first box: 13+2 is 15 and half of 15 is 7.5 so you need to take 13 and subtract 7.5. Once you do that, you end up with 6.5

Explanation for second box: (The negative 7 doesn't matter because you want the absolute value) 18+7 is 25 and half of 25 is 12.5. 18-12.5 is 5.5 so the answer would be 5.5

PLEASE HELP!<br>What is the value of x?
ss7ja [257]

Answer:

84

Step-by-step explanation:

sum of interior angles of a pentagon is 540. A triangle is 180, then for each side you add another 180, so a square would be 360 and a pentagon is 540

Sum up all given sides

131+108+107+110=456

subtract this number from 540

540-456=84

x degree= 84
