Answer:
I don't know the answer but I have an app recommendation that may help you with this assignment and future assignments and it's called: Photomath
sinA+sinB+sinC
=2sin(A+B)/2cos(A-B)/2+sin C
=2sin(pi-C)/2cos(A-B)/2+2sin C/2cosC/2
=2cosC/2(cos(A-B)/2+cos(A+B)/2)
=4 cos A/2 cos B/2 cos C/2
= RHS
Grace annual gross salary is 52($483.75-$170)=$313.75 * 52=$16,315
we multiplied by 52 because we have 52 weeks in a year.
Divide total miles driven by number of gallons of gas used.
243 miles / 9 gallons = 27 miles per gallon
324 miles / 12 gallons = 27 miles per gallon.
She can drive 27 miles on one gallon of gas.
Distribute.
8(y+4)
8y+32= 7y+38
Subtract 32.
8y= 7y+6
Subtract 7y from both sides.
1y= 6
Divide 1 into both sides.
y=6
I hope this helped!
