Answer 1

Answer:

wherever i have made the box is the answer

Answer 2

Step-by-step explanation:

cos(90−10)sin(30)cos(90−40)cos(90−70)

=cos(80)

cos(80)cos(40).2sin(20)cos(20)

=

cos(80)2.cos(40)sin(40)

=

16sin(20)

sin(160)

=

16sin(20)

=cos(80)2/1=cos(80) 2/1=cos(80)2/1

cos(40)cos(20)=4sin(20)1cos(40)cos(20)= 4sin(20)1cos(40)cos(20)=4sin(20)1

cos(80)cos(40).2sin(20)cos(20)=8sin(20)1cos(80)cos(40).2sin(20)cos(20)= 8sin(20)1cos(80)cos(40).2sin(20)cos(20)=8sin(20)1

cos(80)2.cos(40)sin(40)=16sin(20)1cos(80)2.cos(40)sin(40)= 16sin(20)1cos(80)2.cos(40)sin(40)=16sin(20)1

2cos(80)sin(80)=16sin(20)12cos(80)sin(80)= 16sin(20)12cos(80)sin(80)=16sin(20)1

sin(160)=16sin(20)1sin(160)= 16sin(20)1sin(160)=16sin(20)1

sin(20)=16/1sin(20)= 16/1sin(20)=16/1
