all triangles have the angles of 180 degrees, so by that logic, 180-70-30=80.
Answer:
i dunno what that means but i think maybe your keyboard broke so the type of letters is random??
Answer:
D. Open the compass so that the distance from the two points of the compass is wider than half the length of
.
Step-by-step explanation:
To construct a perpendicular for
, we must first take a compass & take the distance of its arms wider than half the length of
.
This is done in order to get two intersecting arcs in the top & bottom of
so that a perpendicular bisector can be drawn through it.
After two intersecting lines are drawn below & above
, draw a line joining these 2 points through their points of intersection. The point where it intersects
is the middle-most point of
& now a perpendicular bisector of
is constructed.

The kinetic energy transfers from the moving ball to the non-moving ball.
