Answer:
20cos(39) or 15.543 (3 d.p.)
Step-by-step explanation:
- Use SOHCAHTOA
- You want to find A and have an angle of 36° and H
- So use CAH
- cos(39) = x / 20
- x = 20cos(39)
Answer:
Step-by-step explanation:
You need to use the following formula for calculate the Surface area of a Right triangular prism:
Where "p" is the perimeter of the base, "h" is the height of the prism and "B" is the area of the base.
You can identify that the height is:
The area of a triangle can be found with this formula:
Where "b" is the height of the triangle and "H" is its height.
Knowing this formula, you can find the area of the base of the prism. This is:
Since the perimeter of a figure is the sum of the lenghts of its sides, "p" is:
Therefore, substituting values into the formula, you get:
