Answer:

$cos{\frac{2\pi}{3}}=-\frac{1}{2}$ .

Reference angle is $\frac{\pi}{3}$

Step-by-step explanation:

Given the value of x. we have to find the correct value of cosx.

$x=\frac{2\pi}{3}$

Now, we have to find the exact value of $cos{\frac{2\pi}{3}}$

$cos{\frac{2\pi}{3}}=cos(\frac{\pi}{2}+\frac{\pi}{6})$

$=-sin(\frac{\pi}{6})$

$=-\frac{1}{2}$

Now, we have to find the reference angle of $x=\frac{2\pi}{3}$ .

Since the angle $x=\frac{2\pi}{3}$ lies in second quadrant, the reference angle formula is

Reference angle= $\pi-given angle$ .

= $\pi-\frac{2\pi}{3}=\frac{\pi}{3}$

last weeekend trisha and becca both went on a bike ride trisha biked 8 miles in two hours and becca biked 10 kilometers in 7800

S_A_V [24]

So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca

A private plane is traveling due east at a rate of 160 mph. A south wind is blowing 30 mph. What is the actual velocity of the p

photoshop1234 [79]

The resultant velocity of the plane is the sum of the two velocity vectors which are perpendicular to each other. See the attached figure.

The magnitude of the resultant velocity is

$\sqrt{160^2+30^2}= \sqrt{26500}=162.79 \;mph$ .

The approximate value of the actual velocity of the plane is $163 \;mph$ . Correct choice is (D).
