Answer:

9. x= 9

10. x= 9

Step-by-step explanation:

9. 13x+12= 129

13x=129-12

x=117/13=9

10.180-(7x-10)= 12x+19

180-7x+10=12x+19

190-7x=12x+19

190=19x+19

190= 19(x+1)

190/ 19=x+1

10=x+1

9=x

Step-by-step explanation:

because line BC divides line DA and line AE into parts with the same ratio to each other (since BC is parallel to DE). This means that (42/21)*17 will give us the length of AB, when we do so, we get 34 as the length of AB.
