A ladder rests against a vertical wall at an inclination α to the horizontal. Its foot is pulled

A ladder rests against a vertical wall at an inclination α to the horizontal. Its foot is pulled away from the wall through a distance p so that its upper end slides a distance q down the wall and then the ladder makes an angle β to the horizontal. Show that p/q = cos β – cos α/sin α – sin β . ‪@2piclasses‬ #2_Pi_Classes #Class10MathsUnit8Exercise8point4NCERTExemplar ________________________________________________________________________ Class 10 chapter 8 maths ncert exemplar ncert exemplar class 10 maths ch 8 ncert exemplar class 10 maths ch 8 ex 8.4 class 10 maths exemplar solutions chapter 8 ncert exemplar class 10 maths trigonometry introduction to trigonometry and its applications class 10 trigonometry ratio class 10 trigonometry class 10 identities trigonometry class 10 cbse ex 8.4 ________________________________________________________________________ Chemistry link: -------------------------- acids, bases and salts class 10-   • ACIDS,BASES AND SALTS CLASS 10 PART 1   carbon and its compounds class 10-   • CARBON AND ITS COMPOUND CLASS 10 PART 1   chemical reactions and equations class 10-   • CHEMICAL REACTIONS AND EQUATIONS PART 1   metals and non metals class 10-   • METALS AND NON-METALS CLASS 10 PART 1   periodic classification of elements class 10-   • METALS AND NON-METALS CLASS 10 PART 1   _____________________________________________________________________ Physics link- --------------------- electricity class 10-   • ELECTRICITY CLASS 10 PART 1   light reflection and refraction class 10-   • LIGHT-REFLECTION AND REFRACTION  CLASS 10 ...   human eye and colourful world class 10-   • THE HUMAN EYE AND THE COLORFUL WORLD CLASS...   magnetic effect of electric current class 10-   • MAGNETIC EFFECT OF ELECTRIC CURRENT CLASS ...   sources of energy class 10-   • renewable and nonrenewable resources of en...   ________________________________________________________________ Maths link- -------------------- real numbers class 10 rd sharma-   • Polynomials Class 10 | RD SHARMA/NCERT | C...   real numbers ncert class 10-   • Видео   polynomials class 10 rd sharma-   • Видео   polynomials class 10 ncert-   • POLYNOMIALS NCERT CLASS 10 |" polynomials ...   Pair of linear equations in two variables class 10-   • PAIR OF LINEAR EQUATIONS IN TWO VARIABLES ...   quadratic equations class 10-   • Видео   arithmetic progressiona class 10-   • ARITHMETIC PROGRESSIONS CLASS 10 || ARITHM...   triangles class 10-   • Triangles | Triangles Class 10 | Class 10 ...   co-ordinate geometry class 10-   • CO-ORDINATE GEOMETRY CLASS 10 PART 1   TRIGONOMETIC RATIOS (RD SHARMA) class 10-   • Introduction - Chapter 6 Class 10 Trigonom...   applications of trigonometry class 10-   • SOME APPLICATIONS OF TRIGONOMETRY CLASS 10...   INTRODUCTION TO TRIGONOMETRY AND ITS APPLICATIONS (NCERT EXEMPLAR)-    • NCERT Class 10 Exemplar Chapter :8 Trigono...   circles class 10-   • CIRCLES CLASS 10 PART 1   constructions class 10-   • CONSTRUCTIONS CLASS 10 PART 1   areas related to circles class 10-   • AREA RELATED  TO CIRCLES CLASS 10 PART 1   surface areas and volumes class 10-   • SURFACE AREAS AND VOLUMES CLASS 10 PART 1   statistics class 10-   • STATISTICS CLASS 10 PART 1   probability class 10-   • PROBABILITY CLASS 10 NCERT PART 1   probability rd sharma-   • PROBABILITY CLASS 10 PART 1   __________________________________________________________________________________________ Thank You !
