If 1000 is the perimeter and 150 is the length what is the width

What is the area of triangle abc if a = 8, b = 11, and c = 15?

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
