Point dis the center of the inscribed circle of a abc. which step can you use to draw the inscribed circle of a abc?
o a. draw arcs of equal lengths intersecting ab. bc, and ac in two points each.
ob. draw the perpendicular bisectors of ab. bc, and ac that pass through point d.
a
oc. label a point eon ab and draw a line joining e with d.
od. draw a line through d that is perpendicular to one of the sides, ab bc or ac.
oe. draw one arc each on ab and bc. and find their point of intersection.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
