It’s D I also trust the other guy
I believe the answer is 5x
Answer:
-6 ≥ r
Step-by-step explanation:
–5 ≥ 5 (r+5)
Divide each side by 5
–5/5 ≥ 5/5 (r+5)
–1 ≥ (r+5)
Subtract 5 from each side
-1-5 ≥ r+5-5
-6 ≥ r
We assume that the dimension 5 has units of feet.
The area of each triangle will be
A = (1/2)bh
where b=2×(5 ft), h=(5 ft)tan(54°)
Then
A = (1/2)(2×5 ft)(5 ft)(tan(54°)
A = 25×tan(54°) ft²
There are 5 such triangles making up this pentagon, so the total area is
total area = 5×25×tan(54°) ft²
≈ 172 ft²
Answer:
Side D is 0.78 feet (to 2 s.f.)
Step-by-step explanation:
In the Scale Drawing, side D=24 centimeters
1 foot = 30.48cm
x foot = 24 cm
Therefore:
24 X 1 = 30.48 X x
x= 24/30.48 =0.7874 feet
Side D is 0.78 feet (to 2 s.f.)
