The answer would be if you only knew one angle and that would be 90 degrees.
The answer is -1296/7. Or in short form -185 1/7
9514 1404 393
Answer:
13.6
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(29°) = 6.6/x
x = 6.6/sin(29°) . . . . . . multiply by x/sin(29°)
x ≈ 13.6
Step-by-step explanation:
At first you need to take its lateral surface area by using the perimeter of base of the triangle and the height of prism.
Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.
Then that's your answer.
First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom.

. Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
