The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:
<span>

</span>So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)
Thank you for the question! I hope this helped! Have an amazing day!! :D

Answer:
x - 11 = 15
Step-by-step explanation:
x is rpthe unknown number
<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
