Here is your answer
![\huge x=\frac{35}{2}cm= 17.5cm](https://tex.z-dn.net/?f=%5Chuge%20x%3D%5Cfrac%7B35%7D%7B2%7Dcm%3D%2017.5cm)
REASON :
AB//CD
So,
/_A=/_D ... (alternate int. angles)
/_B=/_C ... (alt. int. angles)
So,
Tri.ABE~Tri.DCE... (by AA similarity)
Therefore,
Corresponding sides are proportional
i.e.
![\frac{AE}{DE}=\frac{AB}{DC}](https://tex.z-dn.net/?f=%5Cfrac%7BAE%7D%7BDE%7D%3D%5Cfrac%7BAB%7D%7BDC%7D)
![\frac{5}{x}=\frac{4}{14}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7Bx%7D%3D%5Cfrac%7B4%7D%7B14%7D%20)
![x=\frac{5×14}{4}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B5%C3%9714%7D%7B4%7D%20)
![x=\frac{5×7}{2}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B5%C3%977%7D%7B2%7D%20)
![x=\frac{35}{2}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B35%7D%7B2%7D%20)

See photo attached - if my work doesn’t make sense I can explain it, just ask (:
Number 1 is 9.03 Hope this HELPS!!!!!
It is the plus minus sign. It means to do the addition and subtraction.
Examples:
10 <span>± 7 = 17 and 3
15 </span><span>± 5 = 20 and 10
100 </span><span>± 90 = 190 and 10
It is generally used to indicate a possibility of two outcomes. A negative or positive outcome.</span>
Answer:
4.8%
Step-by-step explanation:
First turn it into a fraction. 60/1240. Than we can turn it into an equation 60/1240=x/100. Since 100 is the percent and x is what we need to find. And you now solve to get x=150/31 or 4.8
