Look at the figure below: an image of a right triangle is shown with an angle labeled y If sin y° = 7 divided by q and tan y° =

Andre45 [30]

Answer:

Cosy° = $\frac{r}{q}$

Step-by-step explanation:

From the picture attached,

By applying all trigonometric ratios in the given right triangle,

Siny° = $\frac{7}{q}$ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

tany° = $\frac{7}{r}$ = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Therefore, Cosy° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

Cosy° = $\frac{r}{q}$

Therefore, Cosy° = $\frac{r}{q}$ will be the answer.

From the 12 players who will travel, the coach must select her starting line-up. She will select a player for each of the five p

gizmo_the_mogwai [7]

Answer:

990

Step-by-step explanation:

The center position can be selected in 3 different ways, the other 4 players can be selected in combinations of 11 players (the center is already selected) taken 4 at a time.

By the Fundamental Principle of Counting, there are

$3\displaystyle\binom{11}{4}=3*\displaystyle\frac{11!}{4!(11-4)!}=3*\displaystyle\frac{11!}{4!7!}=990$

ways for her to select the starting line-up.

Can someone help me? I need question #23

weqwewe [10]

Answer:

x = 3; y = 11

Step-by-step explanation:

A parallelogram has two pairs of congruent opposite sides. For quadrilateral ABCD to be a parallelogram, sides AB and CD must be congruent, and sides AD and BC must be congruent.

AB = CD

2y + 2 = 3y - 9

-y = -11

y = 11

AD = BC

3x + 6 = y + 4

We already know y = 11, so we substitute 11 for y.

3x + 6 = 11 + 4

3x + 6 = 15

3x = 9

x = 3

Answer: x = 3; y = 11
