Answer:
2400 miles²
Step-by-step explanation:
Given that:
Area off the coast is rectangular ;
Dimension of location :40 miles by 66 miles
The area of the location will be : the area of a rectangle ;
The area of a rectangle = Length * width
Area = 40 miles * 60 miles
Area = 2400 miles²
Answer:
13, 17, 19, and 23
Step-by-step explanation:
13+17+19+23=72
1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).
Sin x°=Opposite/Hypotenuse
Cos x°=Adjacent/Hypotenuse
2. The inverse of Sinx° is Cosec x°, then:
Cosec x°=1/Sin x°
3. The inverse of Cos x° is Sec x°, then:
Sec x°=1/Cos x°
4. Keeping this on mind, you have:
Cosc x°=Hypotenuse/Opposite
Sec x°=Hypotenuse/Adjacent
5. Therefore, the correct answer is:
The third option: Cosec x°=Hypotenuse/Opposite.
Answer:
Turn off battery supply → The electromagnet turns off.
Place a magnet care inside the coil of wire → The strength of the electromagnet increases.
Change the direction in which the current flows → The poles of the electromagnet reverses
