Answer:
the triangle is acute the angles add up to 180
Step-by-step explanation:
Answer: The angles all add up to 180 degrees, the triangle is obtuse, and it is an isosceles triangle.
Step-by-step explanation: Since the triangle has angles, 40, 40, and 100, the angles will add up to 180. Also since it has an angle more than 90 degrees, the triangle is obtuse. Finally it has two equal sides, so it is a an isosceles triangle. It does not have all equal side lengths, so it is not an equilateral triangle. Also the triangle does not have all different side lengths so it is not a scalene triangle. Finally, the triangle does not have any acute angles (angles under 90 degrees) so the triangle is not acute.
