Find the sides marked with letters in questions 7 and 9 - all lengths are given in centimetres

Answer:
Question 7. e is 7
Step-by-step explanation:
Line AC=LINE AB+BC
Line AC=6+2
Line AC=8
Line CD=6
To find AD use the hypotenuse formula:A squared+B squared =C squared
Base*Base+Height*Height=Hypotenuse*Hypotenuse
Base:6
Height:8
8*8+6*6=Line AD squared
64+36=100
[tex]\sqrt{x}100[/tex] is 10
Line AD is 10.To find e:10-Line ED[3]=7
The answer:7
