If 0°<0<90° and sin0=12/13, find cos0 using trigonometric identities. • 12/5
• 5/12
• 12/13
• 5/13

here's the solution,

we know :

So,

so.. let the perpendicular be 12x and hypotenuse be 13x

now,

by applying pythagoras theorem,

where,

So,

so,

hope it helps !!

is should be y = 5x

step-by-step explanation:

correct me if im wrong
