(b) is the answer.
Step-by-step explanation:
By the Pythagorean Theorem,
A² + B² = C²
Where:
A = Length of side 1
B = Length of side 2
C = Hypotenuse
This rule applies to all right-angled triangles.
The length of the hypotenuse of a right-angled triangle is always the largest value.
Therefore, we can test the answers with the equation above.
(a)
8² + 18² = 20²
64 + 324 = 400
388 ≠ 400
The rule of Pythagorean theorem doesn't work on a, so (a) is not a right-angled triangle.
(b)
12² + 35² = 37²
144 + 1225 = 1369
1369 = 1369
The rule of Pythagorean theorem works here, so (b) is a right-angled triangle.

Answer:
B
Step-by-step explanation:
I know this because 12 dividend by 13 is closer than 9 than any other answer.
Answer:
Step-by-step explanation:
The speed of light is 
and its frequency is 
.
The speed of light is given as:
c = λ * f
where λ = wavelength of light
f = frequency of light
Therefore, the wavelength is given as:
λ = c / f
=> λ = 
=> λ =
The wavelength of the light is
I would assume it's the area of both the sidewalk and pool combined (79ft x 49ft = 3,871) minus the area of the pool alone (75ft x 45ft = 3,375). The area of the sidewalk would then be
496 ft
.
