Question

in triangle abc right angled at B ab is equal to 24 cm BC is equal to 7 cm determine Sin A cos a sin C Kosi​

Answer 1

Answer:

in right angle triangle abc B=90 BC=7cm ab =24cm

by PGT

(h)^=(p)^+(b)^

(h)^= (24) ^+(7)^

(h)^= 576+49

(h)^= 625

h=25

now,

sinC=p\h=24/25

cosC=b/h=7/25

then again,

by PGT

h^=p^+b^

h^=(7)^+(24)^

h^=49+ 576

h^=625

h= 25

now ,

sinA=p/h=7/25

cosC=b/h=24/25
