Answer:
See explanation
Step-by-step explanation:
sin(α + β) = sin α cos β + sin β cos α
sin(α - β) = sin α cos β - sin β cos α
[ sin(α + β) + sin(α - β)] = [sin α cos β + sin β cos α + sin α cos β - sin β cos α]
= [2 sinα cos β]
= sin α cos β = [ sin(α + β) + sin(α - β)]
Because a triangle is 180 degrees, and you already have a right angle that leaves 90 degrees for the rest of the angles.
So, (2x) + (x+15) = 90
Combine like terms.
3x + 15 = 90
Subtract 15 from 90.
3x = 75
Divide.
75/3, so x = 25.
The simplifying of the expression will be -12a+102
If we calculate the net take home pay and we assume the employer withheld federal income tax (wage-bracket, married, 2 <span>allowances), social security taxes, and state income tax (2%)
</span>
Married at least $500 but not more than $510 $21
Social Security at 4.2% $21
State income tax at 2% $10
Total taxes: $52
Total net take-home pay: $598
