1 answer:

4 0

Step 1. Identify the unit you have
Step 2. Identify the unit you want to covert to
Step 3. Count the number of units between them

(If you are going from a larger unit to a smaller unit, you multiply by 10 successively.)

Answer:

sin(θ) = (2/5)√6

Step-by-step explanation:

The sine and cosine are related by the formula ...

$\sin{(\theta)}^2+\cos{(\theta)}^2=1\\\\\sin{(\theta)}=\pm\sqrt{1-\cos{(\theta)}^2}$

Filling in the given value for cos(θ), we find the sine to be ...

$\sin{(\theta)}=\pm\sqrt{1-\left(\dfrac{1}{5}\right)^2}=\pm\dfrac{\sqrt{24}}{5}=\pm\dfrac{2}{5}\sqrt{6}$

The cosine function is positive for angles in both the first and fourth quadrants. The restriction on θ tells us this is a first-quadrant angle. The sine is positive in the first quadrant, so the desired value is ...

sin(θ) = (2/5)√6

Plz help I’ll mark brainliest

timurjin [86]

Answer:

Step-by-step explanation:

Using Pythagoras Theorem, hypotenuse = 5

$h = \sqrt{a^{2}+ b^{2}$

$h = \sqrt{9+16 }\ = \sqrt{25}\ = 5$

sin x = height / hypotenuse = 3 / 5

cos y = base / hypotenuse = 3 / 5

sin x = cos y = 3 / 5

Help asap! ill give the best to person who explains it clearly

Phantasy [73]

Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the area of circle using the formula :

A = π × r²

A = π × 3²

A = 9π

Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :

A = (θ/360) × π × r²

A = (60/360) × π × 3²

A = 1.5π

Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :

A = (9π × 2) - (1.5π × 2)

A = 18π - 3π

A = 15π
