Billy and Judy are working together to find the length of the bridge side DA, to the nearest metre. 34° bridge 85° C A 100 m 67° B Billy says he will first calculate the length of AC using SOH CAH TOA. Next, he will use Sine Law to determine the length of DA. Judy thinks Billy is wrong. She wants to use Pythagorean Theorem first, since AABC is a right angle triangle. She will then use Cosine Law, since AACD forms a SAS pattern. A) Who is correct? Into Blank #1 indicate "Billy" or "Judy"
