Solve using the Pythagorean identity<br>

Lynna [10]

<h3> $\bold{Sin\theta_{1}=-\frac{4}{5}}$ </h3>

Answer:

Solution given

Cos $\displaystyle \theta_{1}=\frac{3}{5}$

consider Pythagorean theorem

$\bold{Sin²\theta+Cos²\theta=1}$

Subtracting $Cos²\theta$ both side

$\displaystyle Sin²\theta=1-Cos²\theta$

doing square root on both side we get

$Sin\theta=\sqrt{1-Cos²\theta}$

Similarly

$Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}$

Substituting value of $Cos\theta_{1}$

we get

$Sin\theta_{1}=\sqrt{1-(\frac{3}{5})²}$

<h3>Solving numerical</h3>

$Sin\theta_{1}=\sqrt{1-(\frac{9}{25})}$

$Sin\theta_{1}=\sqrt{\frac{16}{225}}$

$Sin\theta_{1}=\frac{\sqrt{2*2*2*2}}{\sqrt{5*5}}$

$Sin\theta_{1}=\frac{4}{5}$

Since

In IVquadrant sin angle is negative

$\bold{Sin\theta_{1}=-\frac{4}{5}}$

please answer ASAP, also, who ever answers if first and has the best explination and work will get the BRAINLIEST crown, and a

Scrat [10]

Volume of 1/4 gal

= Volume of 2/3 bin

Volume(x gal)

= Volume( 1 bin)

So, (1/4)/(2/3)

= x/1

(1/4)/(2/3)

= x

(1/4)/(3/2)

x = 3/8 (Total balance required to fill the entire bin)

In order to fill the bin, the additional gallons need to be added to the initial 1/4 gallon

Therefore, 3/8 - 1/4 = 1/8 gallons

Hope that helps!!!!

Write 125 as a repeated multiplication 5s. Then write it as a power.

Maru [420]

Answer:

125 = 5 * 5 * 5 = 5^3

Step-by-step explanation:

125 is equal to 5 times 5 times 5, and a power is a way to write repeated multiplication, just by saying what number it is and the putting a ^ sign and then saying how many times there is that number. There is 5 three times, so the power is 5^3.
