Since TSQ and QSR are supplementary, they give 180 when summed. TSQ is 150, so QSR must be 30.

Therefore, you have

$\tan(30)=\dfrac{\sin(30)}{\cos(30)}=\dfrac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = \dfrac{1}{2}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{1}{\sqrt{3}}=\dfrac{\sqrt{3}}{3}$

Which of the following is NOT possible? A = A triangle where one angle measures 20 degrees and another angle measures 45 degrees

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

the angle measures of triangles must add up to 180 degrees. Since we are only given two angles, we can assume that all of the answers that add up to be below 180 degrees fulfill this requirement with the third angle. However, answer choice C adds up to 190 degrees on the first two angle, which means that no matter how low the third angle is, it will never add up to 180 degrees.

For for every ten sheets of stickers you buy at a craft store the total cost increases $20.50

Len [333]

The equation which relates the change in price per sticker purchased is y = 2.05x

The number of stickers purchased = 10

Price change = $20.50

The change in price per sticker purchased can be expressed as :

Price change / number of stickers

Change in price per sticker = $20.50 / 10

Change in price per sticker purchased = 2.05

Therefore, the required equation which related y and x is :

y = 2.05x

Step-by-step explanation:

>We can do this by splitting the figure into 2 trapeziums.

>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula: $\frac{1}{2} * (a+b) * (total height)$ .
