Please solve for x. Thank you.

Step-by-step explanation:

so the number is 27 + x which is on ST side so the same side is CD. So we put 27 + x = 30

-27       = -27

     x = 3

always look at the pattern of the angles like angle DBC ~ TRS and see what its asking for

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
