Which could be the area of the base of the triangular prism?
[Not drawn to scale)
• 6 ft²
• 10 ft²
• 12 ft²
• 20 ft²
Answer:
6ft²
Step-by-step explanation:
The formula for the base area of a triangular prism is given as:
Area of the base = √s(s-a) (s-b) (s-c)
Where s = (a+b+c)/2
From the attached diagram,
a = 5ft
b = 3ft
c = 4ft
s= (5ft + 3ft + 4ft) ÷ 2
s = 6ft
Area of the base = √ 6( 6-5) (6-3) (6-4)
= √6(1)(3)(2)
= √36
= 6ft²
Therefore, the area of the base of the triangular prism is 6ft²

Answer:
Step-by-step explanation:
Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.
Let the unspecified angle be (This sign is called theta, which is just a sign for angle)
Lets start!
cos = adj/hyp
cos = 6/13
=
(6/13)
= 62.5
= 63
