The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).

Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse

Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse

Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.

The acronym to remember this is SOHCAHTOA

SOH | CAH | TOA

SOH means sin(x) = opposite/hypotenuse

CAH means cos(x) = adjacent/hypotenuse

TOA means tan(x)= opposite/adjacent

cosB = length of adjacent side/length of hypotenuse = 7/25

tanB = length of opposite/length of adjacent = 24/7

sinB = length of opposite/length of hypotenuse = 24/25

so toal cost=28 right?

total cost=total cost of water+total cost of tickets
water=3
subsitute 28=total cost and 3=total cost of water

28=3+total cost of tickets
remember we can do anything to an equaton as long as you do it to both sides

28=3+total cost of tickets
subtract 3 from both sides
28-3=3-3+total cost of tickets
25=0+cost of tickets
25=cost of tickets

if he bought 5 tickets, how much does each cost
25=5tickets
divide both sides by 5
25/5=5/5tickets
5=1tickets

answer is 1 ticket cost $5.00

equation is
total cost=water+tickets
28=3+5tickets

A dinner cost $22 and a sales tax of $1.87 was added to the bill. How much would the sales tax be on a $66 dinner? What is the t

alexdok [17]

Answer:

The correct answer is the sales tax charged is $5.61 for $66 dinner at 8.5% tax rate.

Step-by-step explanation:

Cost of the dinner is $22. Tax levied on it is $1.87

Let x% is the rate of tax in the city.

Therefore, x% of 22 = 1.87

⇒ x = 1.87 × $\frac{100}{22}$ = 8.5
