Solve for θ.
sin(74) = cos(θ)

1. 6°
2. 74°
3. 36°
4. 16° ​

Sin74 = Cos16

cause 16 + 74 = 90

Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :

Sin(30) = Cos(60)

and also

Tan(30) = Cot(60)

16

Step-by-step explanation:

sin(74) = cos(x)

sin(x)=cos(90-x)

sin (74) = cos(90-74)

sin 74 = cos( 16)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
