Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is $\frac{\text{opposite}}{\text{hypotenuse}}$

cosine is $\frac{\text{adjacent}}{\text{hypotenuse}}$

tangent is $\frac{\text{opposite}}{\text{adjacent}}$

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of 2.

kifflom [539]

Answer:

x = 29°

The angles are 137° , 116° , 96° , 44° and 147°

Step-by-step explanation:

The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°, 4x° , 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows

5x – 8° + 4x° + 96° + 44° + 5x + 2° = 540°

collect like terms

5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°

14x + 134 = 540°

14x = 540 - 134

14x = 406

divide both sides by 14

x = 406/14

x = 29°

Therefore, the angles are as follows

29 × 5 - 8 = 137°

29 × 4 = 116°

96°

44°

5 × 29 + 2 = 147°

A person bought some Australian dollar of NRs 1,50,000 according to the exchange rate. Australian dollar 1 = NRs 77.02. After fi

Answer:

5.26% profit (NRs 7,894.24)

Step-by-step explanation:

The exchange of 1,50,000 NRs to A$ will give ...

A$ 1/(NRs 77.02) = x /1,50,000

x = A$ 1,50,000/77.02 = A$ 1947.54 . . . . . (rounded down)

If the Nepali rupees are devalued by 5%, then what did buy A$ 1 will now buy only A$ 0.95. Then the exchange back to NRs will give ...

(NRs 77.02)/(A$ 0.95) = x/(A$ 1947.54)

x = NRs (1947.54)(77.02/0.95) = NRs 1,57,894.24

The effective profit is the difference from the amount initially exchanged, NRs 7,894.24, or ...

(1,57,984.24/1,50,000 -1) × 100% ≈ 5.26%

<em>Additional comment</em>

Except for the loss in the exchange due to rounding down, the profit would be 1/0.95 -1 = 5.2632%. Instead, it is 5.2628%. This is why investors move their money to investments that retain their value when the local currency is losing its value.

Jenny bough 4 combo packs of popcorn and candy for 32$ at the movie theater, what was the cost of each pack?

romanna [79]

Answer:

Step-by-step explanation:

Each pack includes one pack of popcorn and one pack of candy. Since Jenny bought 4 packs, and it cost $32 in total, the equation will look like:

4x = 32

To solve this you divide 4 into each side of the equation:

4x = 32

---- ----

4 4

x = 8

The answer is 8.

Hope this helped.
