Atriangle with vertices at a(0,0),b(0,4),and c(6,0) is dilated to yield a triangle with vertices at a'(0,0),b'(0,10), and c'(15,0). the origin is the center of dilation. what is the scale factor of the dilation.

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°

]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
