#5 Charles claims he can draw a triangle with angle measures of 60°, 130°, and 150°. Which statement about Charles's claim is true?

• It is possible to draw such a triangle because the angles add up to 360°.

• It is possible to draw such a triangle because none of the angles are above 180°.

• It is impossible to draw such a triangle because a triangle cannot contain 2 obtuse angles.

• It is impossible to determine if such a triangle can be drawn without more information on the lengths of the triangle's sides.
