Answer:
Step-by-step explanation:
Triangle CDE is a right angle triangle.
From the given right angle triangle
CE represents the hypotenuse of the right angle triangle.
With ∠C as the reference angle,
CD represents the adjacent side of the right angle triangle.
DE represents the opposite side of the right angle triangle.
To determineTan C, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan C = 80/39
Tan C = 2.0513
Rounding up to the nearest hundredth, it becomes
2.05
6 × 6 × 6
= 216
the answer is c.216
I believe the answer is D
4 is the base because the formula for a triangle is base times height divided by two, you would know that 8 times 4 would equal 32. When divided by 2 it would equal 16 which is the area. So 4 is the answer.
The correct answer is A which is obtuse
