Answer:

Step-by-step explanation:

$sin=\frac{opp}{hyp}$

$cos = \frac{adj}{hyp}$

$cos^{-1}\left(\frac{45}{51}\right)$

which is 28.07 degree

$sin\left(28.07\right)=\frac{x}{51}$

x= 23.99

Answer:

D. x<2

Step-by-step explanation:

-1+ 6-1-3x) >- 39 - 2x

Multiply the parentheses by 6

- 1-6 - 18x > - 39 - 2x

Calculate

7- 18x > - 39 - 2x

Move the terms

18x + 2x > -39 +7

Collect like terms Calculate

- 16x>-32

Divide both sides by - 16

x < 2

Line segment WX is the radius of circle X, and line segment ZY is the radius of circle Y. Points W, X, C, Y, and Z are all on li

Andrews [41]

Point D is the midpoint of the outer circle that we aim to find the area of

The circle has a diameter of WZ and radii of WC and CZ

We know that YZ=YD=10 cm

Let DC be $x$ and CY be $10-x$

The radius of the outer circle can be written as $8+8+x$ or $10+10-x$ which we can equate to find the value of $x$

$8+8+x=10+10-x$
$16+x=20-x$
$2x=4$
$x=2$

Therefore, the radius of the circle is $8+8+2=18$

And hence the area of the circle is $\pi (18^{2})$ =324 $\pi$
