Question

3) Find EC. E-B=49 D-C=16 D-B=30

4)Solve for x. S-V=4x-29 S-T=13 T-U=6 U-V=2x-18​

Answer 1

3)

To find EC,

EC = ED + DC

Find ED = EB - DB = 49 - 30 = 19

Now, given DC = 16

So, EC = 19 + 16 = 35

4)

SV = ST + TU + UV

4x - 29 = 13 + 6 +2x - 18

4x - 2x = 13 + 6 -18 + 29

2x = 30

x = 15
