Step-by-step explanation: go back to 1 grade (sorry)
8x+(4*30)=6(6+30)
8x+120=6x+180
2x=60
x=30 pounds of coffee
Answer:
C
Step-by-step explanation:
Using sum/difference to product identity
• sin x - sin y = 2 cos(
) sin (
)
with x = 4Θ and y = 2Θ
Then
sin(4Θ) - sin(2Θ)
= 2 cos(
) sin(
)
= 2cos(3Θ)sinΘ → C
X = 180 - (90 + 47)
x = 180 - 137
x = 43
answer angle x = 43
