Question

the right angle triangles abc, 8cm,15cm and 17cm are the lengnghts of ab,bc and ca respectively .then ,find out sina, cosa and tan a .

Answer 1

in this base= 8, perpedicular= 15 and hypotaneous= 17
sin a= 15/17 as sin a=perpendicular/hypotaneous
cos a= 8/17 as cos a= base/ hypotaneous
tan a= 15/8 as tan a= perpedicular / base

Answer 2

Ac = 17 cm Ab = 8 cm BC = 15 cm Sin a = perpendicular \ hypotenuse = 8cm\ 17 cm Cos a= base \ hypotenuse = 15 cm \17 cm Tan a = perpendicular \ base = 8cm\ 15 cm
