Patricia, Luca and Dauda shared an amount of money such that, Patricia had twice as much

inn [45]

Answer:

GH 1533

Step-by-step explanation:

Let Dauda's share of the money=x

Patricia had twice as much as Dauda, therefore:

Patricia's share=2x

Luca had GH 600.00 more than Dauda, therefore:

Luca's Share =x+600

If Patricia had GH 2,000.00

Then: 2x=2000

x=1000

Therefore:

Dauda's Share=GH 1000
Patricia's share=GH 2000
Luca's Share =1000+600=GH 1,600

Next, we determine the average share.

$\text{Average Share=}\dfrac{1000+2000+1600}{3}\\=\dfrac{4600}{3}\\\\=$GH 1533.33\\\text{Average Share} \approx $GH 1533 (to the nearest GH)$

So, the sides you are going to be multiplying are opposite and adjacent. The trigonometric function is tangent. So it'll be Tan0

nadya68 [22]

Answer:

54°

Step-by-step explanation:

Multiplication is not involved.

The trig relation that is concerned with the opposite and adjacent sides of an angle in a right triangle is the tangent relation:

Tan = Opposite/Adjacent

tan(θ) = 41/30

The value of the angle is found using the inverse tangent function:

θ = arctan(41/30) ≈ 53.807°

The angle of elevation is about 54°.

<em>Additional comment</em>

The mnemonic SOH CAH TOA is often used as a reminder of the relationship between right triangle sides and trig functions. The other two relations are ...

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

For finding angles, the inverse trig relations are used. These can be called "arcsine," "arccosine," and "arctangent." They are often shown in functional form as (respectively) sin⁻¹, cos⁻¹, and tan⁻¹. On a calculator, they are often "2nd" or "Shift" or "Alt" functions of the sin, cos, and tan keys.
