You are given the steps for using a compass and a straightedge to construct a perpendicular to a given line through a point not lying on the given line. arrange the steps in the proper sequence
geometry

Place compass needle  on external point R

Make compass width greater than distance from R to given line

Draw arc cutting given at 2 points

Mark / label points of intersection P and Q

Don't change compass width, move compass needle to Q, draw another arc below line crossing previous arc

Move compass needle to P , make arc below line

Mark / label point of intersection S.

Draw line from external point R to point where arcs intersect, S

Line RS is perpendicular to line PQ and passes thru external point R

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
