To solve this problem, we need to understand the layout of the ramp. Let's assign points as follows:
A - interior point
B - interior point
C - outside point
D - interior point
1. To compute the distance between points B and C, we can use the Pythagorean Theorem. The distance between B and C is the hypotenuse of the right triangle with sides of 30 inches and 7 inches. Using the Pythagorean theorem, we can calculate:
BC = β(30^2 + 7^2) = β(900 + 49) = β949 β 30.82 inches
So the distance between points B and C is approximately 30.82 inches.
2. To compute the distance between points A and B, we can use the Pythagorean Theorem. The distance between A and B is the hypotenuse of the right triangle with sides of 11 inches and 7 inches. Using the Pythagorean theorem, we can calculate:
AB = β(11^2 + 7^2) = β(121 + 49) = β170 β 13.04 inches
So the distance between points A and B is approximately 13.04 inches.
3. To compute the distance between points D and B, we can simply subtract the length of AB from the length of BC, as D lies on the extension of BC. So,
DB = BC - AB = 30.82 - 13.04 β 17.78 inches
So the distance between points D and B is approximately 17.78 inches.
4. To compute the distance between points D and C, we can use the Pythagorean Theorem again. The distance between D and C is the hypotenuse of the right triangle with sides of 17.78 inches and 30 inches. Using the Pythagorean theorem, we can calculate:
DC = β(17.78^2 + 30^2) = β(315.6484 + 900) = β1215.6484 β 34.89 inches
So the distance between points D and C is approximately 34.89 inches.
