To find the volume of this triangular prism, you first need to find the area of the triangular base. The formula for the area of a triangle is bh/2, which in this case is 3*2/2=3 square units. Multiplying this by the height of the prism, 3.5, you get a total of 10.5 cubic inches, or answer choice d. Hope this helps!
I know for sure, x=110 and the interior of a triangle is 180 degrees added up, so it is definately less than 180 degrees for the 2 angles added up, I am not sure what y is I haven't done geometry for almost 2 years now sorry.
In order to calculate the value of the hypotenuse we use knowledge on trigonometric functions. For this case, we can use the sine function. We do as follows:
