Angelina is starting to save $950 to buy a new phone. In February, she saved $5. In March, she saved twice as much as she saved in February, for a total savings of $15 ($5 + $10). If Angelina continues to save twice as much each month as she saved the previous month, in which month will her total savings be enough to buy the phone? How much will she have saved? Once she purchases the phone, how much will she have left over?

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.

probably .5

i can on others if necessary.

it is 570
