Answer:
21 3/7 mL ≈ 21.43 mL
Step-by-step explanation:
Let x represent the amount of 6% solution that should be added. The the total volume of sodium carbonate in the mix is ...
1%(50) +6%(x) = 2.5%(50 +x)
50 +6x = 125 +2.5x . . . . . multiply by 100, eliminate parentheses
3.5x = 75 . . . . . . . . . . . . . subtract 2.5x+50
x = 21 3/7 . . . . . . . . . . . . . divide by 3.5
21 3/7 mL, about 21.43 mL, of 6% solution should be added to make a 2.5% solution.

I’m really sorry if the answer turned out wrong but I tried my best!
1/2 of angle D is given as 32 degrees.
The 3 inside angles need to add up to 180 degrees.
Angle B is a right angle, which is 90.
Angle C = 180 - 90 - 32 = 58 degrees.
