Answer: x = 7
Step-by-step explanation: In order for a parallelogram to be a square, the angles at the corners must be 90 degrees, and the diagonals that bisect the corner angles must be 45 degrees.
4x + 17 = 45 Subtract 17 from both sides.
4x = 28 Divide both sides by 4
x = 7
Answer:
Step-by-step explanation:
v = f λ,
Where V = velocity, f = frequency and λ = wavelength
1.) What is the wavelength of an electromagneticwave with a frequency of 145,000 Hz?
λ = v/f
Electromagnetic waves have a velocity of 3.0 * 10^8m/s
λ = 300000000/145000
λ = 2,068.97m
2.) What is the wavelength of an electromagnetic wave with a frequency of 165,000 Hz?
λ = v/f
λ = 300000000/165000
λ = 1,818.18m
3.) An electromagnetic wave has a wavelength of0.65 km. What is its frequency?
f = v/λ
f = 300000000/650
f = 461,538.46Hz
4.) An electromagnetic wave has a wavelength of0.45 km. What is its frequency?
f = v/λ
f = 300000000/450
f = 666,666.67Hz
5.) What is the wavelength of an electromagneticwave with a frequency of 225,000 Hz?
λ = v/f
λ = 300000000/225000
λ = 1,333.33m
