For the shoe size be equal to the length of the foot, this means that L must be equal to S. Now, since we have different equations depending on your gender, we first check the conditions for man.
Since S = 3L - 22 for men, for a person to have a foot length equal to his shoe size, we equate L to S as shown below.
L = S
L = 3L - 22
2L = 22
L = 11
Thus, we can see that men with 11-inch foot would have the same shoe size number. We can apply similar approach to find the length of a woman's foot that satisfies our conditions as shown.
L = S
L = 3L - 21
2L = 21
L = 10.5
Hence, a woman with a 10.5-inch foot have 10.5 for a shoe size as well.
Answer:
man: 11 inches
woman: 10.5 inches
Answer:
Step-by-step explanation:
So you know that the triangle is a right triangle, and that means that the work is pretty straightforward:
You 'know' the measure of angle x and one of the legs of the triangle, so when trying to find the distance of the second leg of the triangle, use the Tangent function because the tangent of angle x = opposite leg / adjacent leg.
Since we know the measure of the adjacent leg and the angle measure, solve for the opposite leg's measure:
tanx = opposite / y
opposite = y * tanx
This means that the distance between the Earth and the Moon is equal to the tangent of the angle of the sun's rays between the Earth and Moon times the distance between the Sun and Earth.
