How Do I Solve This (trigonometry)

Answers

Answer 1

Answer:

3/5

Step-by-step explanation:

the sin of an acute angle in a right triangle is the ratio of the opposite side to the hypotenuse

24/40=3/5

Answer 2

Answer:

sine of Z = 36.87 (36.86989765 to be exact)

Step-by-step explanation:

Remember SOH-CAH-TOA

Sine=OH=opposite/hypotenuse.

You want to find the angle of Z so, theta Z= 24/40 (O/H)

On your calculator, put inverse sine(sin ^-1) of 24/40.

So, sin-1 (24/40)=36.87 degrees.

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?

Answers

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

[tex]f+c=290[/tex]

The total income was $95,280. Therefore:

[tex]680f+288c=95280[/tex]

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

[tex]85f+36c=11910[/tex]

From the first equation, we can subtract f from both sides:

[tex]c=290-f[/tex]

Substitute:

[tex]85f+36(290-f)=11910[/tex]

Distribute:

[tex]85f+10440-36f=11910[/tex]

Simplify:

[tex]49f=1470[/tex]

So:

[tex]f=30[/tex]

From the previous equation:

[tex]c=290-f[/tex]

Substitute:

[tex]c=290-30=260[/tex]

30 first-class tickets were sold and 260 coach tickets were sold.

Determine the value of x that would make quadrilateral LMNO a parallelogram.

Answers

Answer:
x=9
Step-by-step explanation:
Diagonals of a parallelogram bisect each other. For quadrilateral LMNO to be a parallelogram, LP must equal PN, and OP must equal PM.
Set OP equal to PM and solve for x.
PM=OP
3x-9=18
Add 9 to both sides.
3x=27
Divide both sides by 3.
x=9

Answer:

9
