What is the surface area of the triangular prism?
TiliK225 [7]

Answer:

<h2>2,376 ft²</h2><h2 />

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 24 ft.

           h = 9 ft.

          s1 = 15 ft.

          s2 = 15 ft.

          s3 = 24 ft.

           L = 40 ft.

<u>plugin values into the formula:</u>

A = 24*9 + 40(15 + 15 + 24)

  = 216 + 40(54)

  = 2,376 ft²

Find the values of the variables in the parallelogram. The diagram is not drawn to scale. (Image is attached below)thank you in
irina1246 [14]

For this problem, we are given a parallelogram with a diagonal drawn, inside it there are markings for a few angles. We need to determine the unknown angles.

Opposite sides of a parallelogram are parallel, this means we can treat the diagonal as a transversal line that crosses two parallel lines. Since this is the case, the angles 33º and xº are alternate interior angles and have the same length:

x=33º

The opposite angles in a parallelogram are congruent, therefore:

z=109º

The sum of internal angles is 360º, therefore we have:

\begin{gathered} 2\cdot109+2\cdot(x+y)=360\\ \\ 218+66+2y=360\\ \\ 284+2y=360\\ \\ 2y=360-284\\ \\ 2y=76\\ \\ y=38 \end{gathered}

The value of x is 33º, the value of y is 38º and the value of z is 109º.
