Answer:
Step-by-step explanation:
∠A + ∠B = 90° {given they are complementary}
5x+ 15 + 30 = 90
5x + 45 = 90
5x = 90 - 45
5x = 45
x = 45/5
x = 9
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
Answer:
$11.10 per gallon.
Step-by-step explanation:
There are 4 quarts in a gallon so the cost of a gallon of oil currently is 1.85×4=$7.40
If the gallon price of oil goes up 50% then our answer is: 7.40×
=
=11.1
The price of oil in March will be $11.10 per gallon.
