Answer:

Step-by-step explanation:

The sum of the angles is 360 degrees since this is a quadrilateral

x+2x+80+145 = 360

Combine like terms

3x +225 = 360

Subtract 225 from each side

3x+225-225 = 360-225

3x =135

Divide each side by 3

3x/3 = 135/3

x =45

We want to find angle S

S = 2x = 2(45) = 90

Calculate cos(480°) and sin(480°).

hram777 [196]

Answer:

$\cos(480^\circ)=-\dfrac{1}{2}$

$\sin(480^\circ)=\dfrac{\sqrt{3}}{2}$

Step-by-step explanation:

Calculate the value of trigonometry function.

$\cos(480^\circ)$ and $\sin(480^\circ)$

Split the angle between 0 to 90° using trigonometry formula.

$\Rightarrow \cos(360^\circ+120^\circ)$

$\Rightarrow \cos(120^\circ)$ $\because \cos(360+\theta)=\cos\theta$

$\Rightarrow \cos(180^\circ-60^\circ)$ $\because 120=180-60$

$\Rightarrow -\cos(60^\circ)$ $\because \cos(180-\theta)=-\cos\theta$

$\Rightarrow -\dfrac{1}{2}$

Therefore, cos(480°) = -0.5

$\Rightarrow \sin(360^\circ+120^\circ)$

$\Rightarrow \sin(120^\circ)$ $\because \sin(360+\theta)=\sin\theta$

$\Rightarrow \sin(180^\circ-60^\circ)$ $\because 120=180-60$

$\Rightarrow \sin(60^\circ)$ $\because \sin(180-\theta)=\sin\theta$

$\Rightarrow \dfrac{\sqrt{3}}{2}$

Therefore, sin(480°) = 0.866

Sedaia [141]

Answer:

x = 15/p

Step-by-step explanation:

4(px + 1) = 64

4px + 4 = 64

-4 -4

4px/p = 60/p

4x/4 = 60/p/4

x = 15/p
