I'll take a shot at this, but it's all assumptions and guesswork, since the question is so ambiguous:
-- The question doesn't state how many sides the figure has, or whether the 'b' is an angle or a side.
-- Assume that we're working with a right triangle, because the question uses the word "hypotenuse".
-- Assume that the 'b' it's asking for is another angle, besides the 40-degree angle given.
-- If it's a triangle, then the sum of the 3 interior angles is 180 degrees.
-- If it's a right triangle, then one of the interior angles is 90 degrees.
-- The missing angle is [ 180 - 90 - 40 ] = 50 degrees.
The length of the hypotenuse makes no difference, but we're very happy that
you said the magic word "hypotenuse".
A right triangle with a hypotenuse of 12cm and an angle 30 degrees has an opposite angle of: 60 degrees.
The hypotenuse of a right (angled) triangle is the side opposite the right (90 degree) angle. The hypotenuse is also the longest side.The hypotenuse of a right triangle is the side opposite theThe sine of an angle is the side opposite over the hypotenuse of the triangle.
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
The side opposite the right angle of a right angle triangle is the hypotenuse
It is the angle opposite the hypotenuse which measures 90 degrees

The hypotenuse of a right (angled) triangle is the side opposite the right (90 degree) angle. The hypotenuse is also the longest side.The hypotenuse of a right triangle is the side opposite theThe sine of an angle is the side opposite over the hypotenuse of the triangle.
The hypotenuse of a right angle triangle is opposite to its right angle of 90 degrees.
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
The side opposite the right angle of a right angle triangle is the hypotenuse
It is the angle opposite the hypotenuse which measures 90 degrees
The side opposite the right angle is called the hypotenuse.
In a right angle triangle the hypotenuse is the largest side because it is opposite to the largest angle which is 90 degrees.
For a right angle triangle its hypotenuse is opposite its angle of 90 degrees and its other two angles are acute and its 3 angles add up to 180 degrees.
A triangle with an hypotenuse has a right angle that measures 90 degrees and two other acute angles,
The only triangle that has a hypotenuse is a right-triangle. The hypotenuse is the side opposite the right angle, so the angle is always 90 degrees. In this case, if you're just finding the angle then you don't need to know what the side lengths are.
