Answer:
Cos;
26 degrees
Step-by-step explanation:
Recall: SOH CAH TOA
Reference angle = y°
Adjacent side = 18 in.
Hypotenuse = 20 in.
We would apply the trigonometric function CAH since we are dealing with the Adjacent side (A) and the Hypotenuse (H). Thus:
Cos y° = Adj/Hyp
Cos y° = 18/20
Cos y° = 0.9
y° = cos^{-1}(0.9)
y = 25.8419328° ≈ 26 degrees (nearest whole degree)
The answers are:
Cos and 26 degrees
Answer:
6π units
Step-by-step explanation:
Given::
Radius = 4
Angle measure of partial circle (θ) = 360° - right angle = 360° - 90° = 270°
Arc length = θ/360 × 2πr
Plug in the values
= 270/360 × 2 × π × 4
= 0.75 × 8 × π
= 6π units
Answer:
the answer is 80 i think
Step-by-step explanation:
bc dependng on 2lw+2lh+2hw, formula 8 and 10 would be length and width
Lets say
8=width
10=lenght
3in=height
u would do
2 x l x w + 2 x l h + 2 x h x w=
2 x 10 x 8 + 2 x 10 x 3 + 3 x 8=
160 + 60 + 48+=
268 is the sa

Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = 
If 
= 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
