I need complete working/steps for part (ii) only. The answer for part (ii) in the book is 1.72 m. Please tell me how to do it. It's the chapter of Pythagoras Theorem. (ii) The upper end of the pole, P, slides down 0.9 m to a point on the wall, X. Calculate YR, the distance the lower end of the pole has slid away from its original position R. ​

Which of these angles are complementary? a. 45o and 45o b. 63o and 117o c. 45o and 135o d. 90o and 45o

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?

Atriangle has side lengths of x, x+11, and 3x+5. what is the perimeter? a. 3x^2 + 38x + 55 b. 4x + 16 c. 5x + 16 d. 3x^3 + 38x^2 + 55x
