Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle,
DE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
EF represents the adjacent side of the right angle triangle.
DF represents the opposite side of the right angle triangle.
To determine EF, we would apply
trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 49 = EF/8
EF = 8Cos49 = 8 × 0.6561
EF = 5.2488
Rounding to the nearest tenth, it becomes 5.2

Step-by-step explanation:
The relationship is y = 3x
Answer:
D
Step-by-step explanation:
SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area
b is base, h is height (small height), s's are the sides, H is the height (longer one)
SA = 12(9) + (10 + 10 + 12)32
SA = 108 + (32)32
SA = 108 + 1024
SA = 1132
The number of lateral faces for a hexagonal prism or pyramid is 6.
<h3>What is a
prism?</h3>
A prism is a three dimensional figure consisting of pair of opposite bases and lateral faces which are parallelogram.
Given that the base off the prism has two sides of length 3 inches and four sides of length 2 inches. Hence the base is hexagonal. The lateral faces would be 6.
The number of lateral faces for a hexagonal prism or pyramid is 6.
