Idont really know how to do soh cah toah. me find x.

First notice that the triangle with sides and the triangle with sides are similar. This is true because the angle between sides in the smaller triangle is clearly , while the angle between sides in the larger triangle is clearly . So the triangles are similar with sides corresponding to , respectively.

Now both triangles are , which means there's a convenient ratio between its sides. If the length of the shortest leg is , then the length of the longer leg is and the hypotenuse has length .

Since is the shortest leg in the larger triangle, it follows that , so

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
