Answer:

x=37

Step-by-step explanation:

You know all the angles in a triangle add up to 180.

Therefore, you add 72° and 71° which equals 143.

Then you subtract 180 and 143 which equals 36.

[72+71=143

180-143=37]

I hope this helps you!

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= $\pi-given angle$ .

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

Your answer would be, What is about 241.

Simplify
516 * 21/45

= ( 516/1) (21/45)
= (516/1) (7/15)

= (516)(7)/(1)(15)
= 3612/15

= 1204/5 (Decimal: 240.8) rounded to about 241

1204 divided by 5 equals 240, with a remainder of 4. 240 r 4, 240 4/5

Answer round to about : 241

Hope this helps!!!! Hope that what you are looking for, I tried my best to help!!!

Multiply the exponents.
So 10 ×4/5=
40/5
=8
Thus (243k^10)^4/5 is 243k^8
