    it's acute as every angle is less than 90

    Sum of all angles of a triangle equals 180\(^o\). So, we have an equation! \[2x +2x +4x = 180\] What's 'x'?

    Also you could do it this way - if you remember that it's only in a right angle where the sum of two angles add upto the third --> 2x + 2x = 4x here. so, a right triangle!
