Answer:
Part A = 90
Part B = 145
Step-by-step explanation:
For part A, we know that a triangle has a sum of 180 degrees. So we just add the angles we already know and then subtract them from 180. For part B, we know that angle ACB and angle ACD are supplementary angles, meaning they add up to 180 degrees. So just take 180 and subtract 35 to find the measure of angle ACD.

Answer:
   x = 7
Step-by-step explanation:
We can write a proportion relating the short segment to the full length:
   (x+1)/18 = 4/(4+5)
   x +1 = 8 . . . . . . multiply by 18 and simplify
   x = 7 . . . . . . . .  subtract 1
