That's of course the sum angle formula for sine
sin(a+b) = sin a cos b + cos a sin b
We have a=20° b=40°
sin 20° cos 40° + cos 20° sin 40°
= sin(20°+40°)
= sin(60°)
= √3/2
Answer: √3/2
Answer:
Variant b
Step-by-step explanation:
If you multiply it should be a+b but if you divided
A+b-c
The new graph will go down 4 point so y coordinate will go down 4. (-6,5) becomes ( -6, 1)
Answer: 1.1
1.01 x 1.1 = 1.111
I hope this is good enough:
