Ascale of a room in a blueprint is 3 in.: 5 ft. a wall in the same blueprint is 18 in. how long is the actual wall? a window in the room has an actual width of 2.5 feet. find the width of the window in the blueprint.

A scale of a room in a blueprint is 3 in.:5 ft. A wall in the same blueprint is 18 in.  How long is the actual wall?  30 feet

A window in the room has an actual width of 2.5 feet. Find the width of the window in the blueprint. 1

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
