Angles α and β are angles in standard position such that: α terminates in Quadrant II and sinα = 3/5, β terminates in Quadrant I
777dan777 [17]

We are given

Angles α and β are angles in standard position

and

α terminates in Quadrant II

β terminates in Quadrant I

and we have

sin(\alpha)=\frac{3}{5}

we can use triangle and find cos(α)

we get

cos(\alpha)=-\frac{4}{5}

and we have

cos(\beta)=\frac{4}{5}

we can draw triangle

sin(\beta)=\frac{3}{5}

now, we can use formula

cos(\alpha+\beta)=cos(\alpha)cos(\beta)-sin(\alpha)sin(\beta)

now, we can plug values

cos(\alpha+\beta)=-\frac{4}{5}\times \frac{4}{5}-\frac{3}{5}\times \frac{3}{5}

now, we can simplify it

cos(\alpha+\beta)=-\frac{16}{25}-\frac{9}{25}

cos(\alpha+\beta)=-\frac{(16+9)}{25}

cos(\alpha+\beta)=-\frac{(16+9)}{25}

cos(\alpha+\beta)=-\frac{25}{25}

cos(\alpha+\beta)=-1...............Answer

Are these ratios proportional? prove it<br> 5/9 = 25/18<br> the / are fractions
Natali [406]

5/9 = 25/18

Cross multiply:

5 * 18 = 9 * 25

Simplifying

5 * 18 = 9 * 25

Multiply 5 * 18

90 = 9 * 25

Multiply 9 * 25

90 = 225

Solving

90 = 225

No they are not

What is 60% of 33= the fraction
olchik [2.2K]
<h2>Answer: </h2><h2>99/5</h2><h2>~</h2><h3>Convert to a mixed number by placing the numbers to the right of the decimal over 10. </h3><h3>Reduce the fraction. </h3><h3>Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. </h3><h3>Place this new numerator over the original denominator to get:</h3><h3>99/5</h3><h3>Or</h3><h3>\frac{99}{5}</h3><h2>~</h2>
