Which relationship in the triangle must be true?

sin(b) = sin(a)
sin(b) = cos(90 – b)
cos(b) = sin(180 – b)
cos(b) = cos(a)

sinB=cos(90-B)

Step-by-step explanation:

this is the relationship between sin and cos. other choices are wrong

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

is it i think
