Step-by-step explanation:
solution:- from LHS 1-cos²x/sinx
∵ 1-cos²x = sin²x
∴ sin²x /sinx = sinx
from RHS tanx × cosx
∵tanx = sinx×cosx
∴ sinx/ cosx × cosx = sinx
Since, LHS = RHS proved ___

Answer:
BC = 22
Step-by-step explanation:
<b = <c given
we now know it is an isosceles triangle
therefore AC = AB
AC=AB
2x-24 = x-2
subtract x from each side
2x-x-24 = x-2-x
x-24 =-2
add 24 to each side
x-24+24 = -2+24
x = 22
side BC = x
BC = 22
