Use a net to find the surface area of the right triangular prism shown:
vazorg [7]

The surface area of the right triangular prism is 270 sq ft

<h3>Total surface ara of the prism</h3>

The total surface area of the prism is the  sum of all the area of its faces

For the two triangles

A = 2(0.5bh)

A = bh

A = 7 * 12 = 84 sq.ft

For the two rectangles

A = 2lw

A = 2(6*12)

A = 2 * 72 = 144 sq.ft

For the third triangle;
Area  6ft * 7ft

Area = 42 sq.feet

Taking the sum of the areas

TSA = 84 + 144 + 42

TSA  = 270 sq ft

Hence the surface area of the right triangular prism is 270 sq ft

Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

\sin( \beta )  =  \frac{ \sqrt{17} }{5}

So, this means that

\sin( \frac{ \beta }{2} )  =  \sqrt{ \frac{1 -  \frac{ \sqrt{17} }{2} }{2} }  =  \sqrt{ \frac{2 -  \sqrt{17} }{4} }  =  \frac{ \sqrt{2 -  \sqrt{17} } }{2}
