The value for y is 17.5°
The equation is
Sin (3y - 30°) = Cos (7y +50°)
<h3>What is Trigonometry ?</h3>
Trigonometry is the branch oh Mathematics which involve the study of right angles , its sides and trigonometric ratios.
the equation given in the question is
Sin (3y - 30°) = Cos (7y +50°)
cos(90 -
) = sin 
Therefore
sin(3y-30°) = sin( 90-(7y+50°)
Equating the terms
3y - 30 = 90-7y -50
4y = 90-50+30
4y = 120-50
4y = 70
y = 17.5
The value for y is 17.5°

7/8 of a pound is 14oz
So if 14oz is 2/3 of the whole bag, you can divide 14oz by 2 to get the weight of 1/3 of the bag (Which is 7oz)
14oz + 7oz = 21oz total pounds of cashews in the bag
