Someone please help out. How do I solve this?

b = 15

Step-by-step explanation:

since line UV and TW are congruent you can take both of numbers on those lines and turn it into an equation.

2b - 15 = b

first, subtract 2b from both sides, you're left with -15 = -b

then, divide each side by -1

-15 divided by -1 turns it into a positive 15 which is b.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
