You are correct
Answer:
42
Step-by-step explanation:
Answer: D. 44
Step-by-step explanation:
Here, we need to know the concept of trigonometry.
- Sine (sin) = Opposite/Hypotenuse = O/H
- Cosine (cos) = Adjacent/Hypotenuse = A/H
- Tangent (tan) = Oppostie/Adjacent = O/A
-----------------------------------------------------------------------------
Given
- The adjacent side of angle x and the hypotenuse.
- We are going to use Cosine.
<u>Solve</u>
cos (x) = 15/21
x = cos⁻¹ (15/21)
x ≈ 44
Hope this helps!! :)
Please let me know if you have any questions
1. You have the following information:
- <span> The square has the same area as a rectangle.
- The dimensions of the rectangle are: 14 mm long and 16 mm wide.
2. You must use the formula for calculate the area of a square, which is shown below:
A=S</span>²
"A" is the area of the square.<span>
"S" is the lenght of the side of the square. (It is important to remember that the sides of a squre have equals lenghts.
3. The square and the rectangle have the same area. Therefore:
Arectangle=(14 mm)(16 mm)
Arectangle=224 mm</span>²
<span>
A=224 mm</span>²
<span>
4. Now, you must substitute the value A=224 mm</span>² into the formula A=S² and clear "S":
<span>
A=S</span>²
<span> S=</span>√A
<span> S=</span>√(224 mm²)
<span> S=15 mm
The answer is: 15 mm
