Answer 11

u will multiply (x+8) with 20.

Answer 12

and then what?

Answer 13

20(x+8) = 26x

20x + 160 = 26x

6x = 160

x = 160/6
x = 26.66

Answer 14

finally,
26.66 - 8
equals
18.88

Answer 39

your last problem - is that the one with sides 20, 6 and 8 and x in the circle

Answer 40

the two large triangles are similar so you can equate ratius of corresponding sides
so (8+ x) / 26 = 6/8
x comes to 11.5
