Answer:
Step-by-step explanation:
So, for 60 square feet they charge = 287
So, for 1 square foot they charge =
If they charge the installation fee this becomes =
We can write an equation to calculate cost by using this
Where x is the amount of square foot
Answer: Missing parts are,
In first blank, ,
In second blank, SAS postulate
In third blank, CPCTC postulate
Step-by-step explanation:
Since, Here D is the mid point on the line segment AC.
And BD is a perpendicular to the line AC.
Therefore, In triangles ADB and CDB ( shown in figure)
AD\cong DC ( By the definition of mid point)
( right angles )
( reflexive)
Thus, By SAS ( side angle side )postulate,
So, by CPCTC( Corresponding parts of congruent triangles are congruent)
Now, By definition of congruent segment,
AB=CB
By definition of equidistant,
B is equally far from both A and C.
