ABC and CBH are right angles

DBC = 90 - 37 = 53
CBJ = 90 - 31 = 59

HBD = 180 - 37 = 143
or
HBD = 31 + 53 + 59 = 143 :)

Answer:

The length of side <em>b</em> is 9.

Step-by-step explanation:

Triangles are similar if they have the same shape, but can be different sizes.

When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. We know that the triangle ABC is similar to the triangle XYZ. Therefore the following relation must be true:

                                                      \frac{AB}{AC} =\frac{XY}{XZ}

We know that side AB is equal to 8, side AC is equal to <em>b, </em>side XY is equal to 2\frac{2}{3}, and side XZ is equal to 3.

Substituting these values into the above relation and solving for <em>b</em> we get that:

\frac{8}{b} =\frac{2\frac{2}{3} }{3}\\\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 2\frac{2}{3}=\frac{8}{3}\\\\\frac{8}{b}=\frac{\frac{8}{3}}{3}\\\\8\cdot \:3=b\frac{8}{3}\\\\24=b\frac{8}{3}\\\\8b=72\\\\b=9

Step-by-step explanation:

{x}^{2}  = 2  \times {4}^{2}  \\  {x}^{2} = 32 \\ x  =  4 \sqrt{2}   \\ diameter = 4 \sqrt{2}  \\ radius = 2 \sqrt{2}  \\ area \: of \: half \: of \: the \: circle =  \\

a =  \frac{\pi \times {(2 \sqrt{2} )}^{2}  }{2}  = 4\pi \\ area \: of \: triangle \:  =  \\ 2 \sqrt{2}  \times 2 \sqrt{2}  = 8 \\ area \: of \: shaded \: region \: is \:  =  \\ 4\pi - 8 = 4.57 \:  {cm}^{2}
