Answer:
14
Step-by-step explanation:
To find the surface area of the triangular prism, simply find the area of the triangular face, and multiply that by a value of 2, to obtain the total surface area for the triangular faces, then find the area of the rectangular faces, by using that formula, do this 3 times for the 3 rectangular faces.
Then add up all of the surface areas of the rectangles, and triangles together to find the total surface area.

Law of sines can be used to solve this problem:
(note - let x represent the missing side length.)
1. set up proportion.
sin 90°/25 = sin 55<span>°/x
2. solve.
(x) sin 90</span>° = (25) sin 55<span>°
(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
