Select the correct answer from each drop-down menu.
an art curator records statistics about three new exhibits at her art museum. the mean age of the artifacts and the standard deviation, sd, for each exhibit are recorded in the table below.
exhibit a exhibit b exhibit c
mean = 42
sd = 4.9 mean = 96
sd = 3.7 mean = 234
sd = 6.1
use the information in the table to complete the following statement.
exhibit shows the least consistency in the age of the artifacts in the exhibit, because its is the

answer: the answer is 127 degrees

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.
