tim started feeding his dog a new brand of food. after the six months, his dog had lost 2 pounds. after the next six months, his dog had gained 2 pounds. what is his dogs next weight change after one year?

Step-by-step explanation:

Given

Required:

Determine the net weight change

The weight lost will be treated as negation.

So, the net weight change (N) is:

Substitute values for weight gained and lost

Hence, the net weight change is 0

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.
