Answer» Here, in the value of x, (√6 +) is repeating endlessly. So from right to left, as each square root is being PASSED through, the value always should be x. ∴ We can also write it as x = √(6 + x). $x = \sqrt{6 + \sqrt{6 + \sqrt{6 + \sqrt{6 + ....}}}} = \sqrt{6 + x} \\ \\ x^2 = 6 + x \\ \\ x^2 - x = 6 \\ \\ = x(x - 1) = 6 = 3 * 2 = 3(3 - 1) \\ \\ \therefore x = 3$ The same is done in the CASE of y. $y = \sqrt{56 + \sqrt{56 + \sqrt{56 + \sqrt{56 + ....}}}} = \sqrt{56 + y} \\ \\ y^2 = 56 + y \\ \\ y^2 - y = 56 \\ \\ = y(y - 1) = 56 = <klux>8</klux> * 7 = 8(8 - 1) \\ \\ \therefore y = 8$ x + y = 3 + 8 = 11 11 is the answer. Hope this may be helpful. Please mark my answer as the BRAINLIEST if this may be helpful. Thank you. Have a nice DAY.

Answer»

Here, in the value of x, (√6 +) is repeating endlessly. So from right to left, as each square root is being PASSED through, the value always should be x.

∴ We can also write it as x = √(6 + x).

$x = \sqrt{6 + \sqrt{6 + \sqrt{6 + \sqrt{6 + ....}}}} = \sqrt{6 + x} \\ \\ x^2 = 6 + x \\ \\ x^2 - x = 6 \\ \\ = x(x - 1) = 6 = 3 * 2 = 3(3 - 1) \\ \\ \therefore x = 3$

The same is done in the CASE of y.

$y = \sqrt{56 + \sqrt{56 + \sqrt{56 + \sqrt{56 + ....}}}} = \sqrt{56 + y} \\ \\ y^2 = 56 + y \\ \\ y^2 - y = 56 \\ \\ = y(y - 1) = 56 = <klux>8</klux> * 7 = 8(8 - 1) \\ \\ \therefore y = 8$

x + y = 3 + 8 = 11

11 is the answer.

Hope this may be helpful.

In the school function, 968 students were made to sit in a hall such that the number of rows is equal to the number of students in each row. Find the number of rows if 7 students were left out after the arrangement.

Answer»

Given that number of students = 968.

Given number of students left out = 7.

Number of students ARRANGED in rows and columns = 968 - 7

= 961.

Given number of rows = number of students in each row.

$= > \sqrt{961}$

$= > \sqrt{31^2}$

$= > 31$

Therefore, the number of rows = 31.

Hope this helps!

31.	10th maths triangle theorem
Answer» All congruent figures are SIMILAR, but it does not mean that all similar figures are congruent. Two polygons of the same number of sides are similar, if: Their corresponding angles are equal. Their corresponding sides are in the same ratio. Two triangles are similar, if: Their corresponding angles are equal. Their corresponding sides are in the same ratio. According to Greek mathematician Thales, "The ratio of any two corresponding sides in two equiangular triangles is always the same." If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio. If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side. If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar. If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar. If in two triangles, sides of one triangle are proportional to the sides of the other triangle, then their corresponding angles are equal and hence the two triangles are similar. If one ANGLE of a triangle is equal to one angle of the other triangle and the sides including these angles are proportional, then the two triangles are similar. The ratio of areas of two similar triangles is equal to the SQUARE of the ratio of their corresponding sides. If a PERPENDICULAR is drawn from the vertex of the right angle of a right triangle to the hypotenuse then triangles on both sides of the perpendicular are similar to the whole triangle and to each other. In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. According to the Indian mathematician Budhayan, "The diagonal of a rectangle PRODUCES by itself the same area as produced by its both sides (i.e., length and breadth)." In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. If in a triangle, square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle.
