Finding maximum in interference pattern

[Les talons]

Homework Statement

In a three-slit system, the first minimum occurs at an angular position of 5.00°. Where is the first maximum?

Homework Equations

dsinθ = mλ/N

The Attempt at a Solution

dsin5° = λ
dsinX = λ/3
sinX = 3sin5°
X = 1.66°

I'm not sure if this is the right equation to find the first maximum in the interference pattern. Also, is the maximum the bright region and the minimum the dark region? Thanks all.

I get 15,2^o when I solve for X?
But your approach is correct, yes.
And yes, the maximum (intensity) is the bright region
and the minimum (intensity of light) is the dark region.

Oh geez, what a silly mistake of dividing by three instead of multiplying by three... Thanks for the feedback.
