Add them all up, and divide by 10 so 29+38+39+26+29+29+39+77+38+29 which is 33.5

Find x<br> A. 22√2<br> B. 22<br> C. 11√3/3<br> D. 11√3

Answer

$22\sqrt{2}$

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

$sin(45)=\frac{11}{Y} \\$ , Because sin(x)= op/hip

$cos(60)=\frac{Y}{x}$ , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

$Y=\frac{11}{sin(45)} \\Y=cos(60)*x$

we equal Y and solve

$\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\$

Then we rationalize

$x=22\sqrt{2}$

Make b the subject.

sp2606 [1]

First, square both sides. This will cancel out the radical.
$a^2 = b \add 6$
(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6
