Suppose that a college of engineering has seven departments, which we denote by a, b, c, d, e, f, and g. a. each department has one representative on the college’s student council. from these seven representatives, one is to be chosen chair, another is to be selected vice-chair, and a third will be secretary. how many ways are there to select the three officers? b. three of the seven representatives are to be selected to attend a statewide convention. how many ways are there to select the three officers? c. which one of these do you think will have more objects in the collection?

i hope this you : d

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.
