A= 4 B= 2 C= -1
follow the formula ax^2 + bx + c= 0.
Answer: I wrote the answer in docs so here is the pic for the whole equation i explained it too! I hope this helped
No it far 10 is way out there
Answer: R=V
Step-by-step explanation: :p
C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))
