sin θ = opposite/hypotenuse & tan θ = opposite/adjacent
sin 30 = 18/y tan 30 = 18/x
y = 18/sin 30 x = 18/tan 30
y = 36 x ≈ 31.2
you can also use the 30° - 60° - 90° shortcuts
side opposite 30 = a, side opposite 60 = a√3, side opposite 90 = 2a
then, 18 = a
x = a√3= 18√3
y = 2a = 2(18) = 36
(this is what I think) Every 40 miles,the car uses 1 gallon,Try doing 750/40=18.75 if not,try figuring out how much gas he uses in 18.75 gallons.
Answer:
Step-by-step explanation:
When looking at fractions, a larger denominator means that the numerator is divided by a larger amount, making it smaller. 7/4 is positive, so we already know it goes last. -3/16 has a larger denominator than -3/8, but in this case, because -3/16 is closer to zero. This means that in order, these fractions would be -3/8, -3/16, 7/4. Hope this was helpful.
