Answer»

C (2) is the correct answer.

2 is the best answer

Let A=45, B=30

b is the best answer

2 is the correct answer

option b is the correct answer

sin(A+B)=sinAcosB+cosAsinAA=45, B= 30°sin(75)=(sin45+30)=sin45 cos30+ cos45 sin30=1/√2(√3/2)+1/√2×1/2= √3/2√2+1/2√2=(√3+1)/2√2option b is right

b. √3+1/2√2 the correct answer

c is the right answers

(d) 2√2 answer your question

c.(2) is the right answer
