Calculate the area of triangle abc with altitude cd, given a (6, -2), b (1, 3), c (5, 5), and d (2, 2). . a. 12 square units. b. 13 square units. c. 13 square units. d. 15 square units

Geometry in the diagram, ∠abc is a right angle. ∠dbc = 30°27'40". find the measure of ∠abd.

What is the difference between the equations of a vertical and a horizontal line?

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
