AB + AD = 47
Периметр треугольника АВС равен…
The perimeter of triangle ABC is equal to the sum of its sides. In this case, the perimeter of triangle ABC can be calculated by adding the lengths of AB and AD together and then adding to it the remaining length of BC. Therefore, the perimeter of triangle ABC is AB + AD + BC = 47. To find the length of BC, we can use the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). Applying this theorem to triangle ABC, we can write BC² = AB² + AC². Since we already know that AB + AD = 47 and AB² + AC² = BC², we can solve for BC by substituting the values and solving the resulting equation. Once we have the value of BC, we can plug it back into the formula for the perimeter to get the final answer. Don't forget to double check your calculations and units! Good luck!
