An air conditioning repair service call costs $75 per hour plus a flat fee trip change of $25. If the situation can be represented by the function r(h)=75h+25, what do the variables represent and which is the dependent variable

A. The repair time h depends on the repair changes r in hours
B. The repair changes h depends on the repair time r in hours
C. The repair changes r depends on the repair time h in hours
D. The repair time r depends on the repair time h in hours

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.
