In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving DC || AB, given AB = CD and AD = CB. Upload the entire proof below. Given: AB = CD AD = CB Prove: DC || AB STATEMENT REASON 1. 1. 2. AC = AC 2. 3. 3. SSS (Side-Side-Side) 4. â 1 = â 4 4. 5. 5.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

something over 10 so ? /10
