Now David wants to solve the equation 4000x - 8000 = 16,000.
a.
What easier equation could he solve instead that would give him the same
solution? (In other words, what equivalent equation has easier numbers to
work with?)
b.
Justify that your equation in part (a) is equivalent to 4000x - 8000 = 16,000
by showing that they have the same solution.
c.
David's last equation to solve is 180 + 180 = 186 . Write and solve an
equivalent equation with easier numbers that would give him the same
answer.

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.

if you was gonna solve for a, a is a   < -12
