Twelve square tiles, each measuring 6 4/5 inches on a side, are laid side by side. What is the total width of the tiles?

81.6 inches or  

Step-by-step explanation:

Given : There are 12 square tiles .

To Find: What is the total width of the tiles​

Solution :

Dimension of each square tile =

Thus the width of 1 tile =  

So, total width for 12 tiles =  

                                         =  

Hence the total width of tiles is 81.6 inches or  

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
