Answer:

180.

Step-by-step explanation:

Given

x = 1%2F2y

x+y=180

...

Substitute x into the second equation and solve for y, the larger angle

1%2F2y + y = 180

Multiply both sides by 2 to be rid of the fraction

y + 2y = 360

3y = 360

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.
