A tourist in a sightseeing balloon drops his cell phone from a height of 920 feet above the ground (see picture). Find the time t (in seconds) for the object to reach the ground. The height (above ground) of the
object is modeled by
Height = - 167² +920
920 feet
How many seconds will it take the object to hit the ground?
seconds (round to 5 decimal places.)
(If you are curious about the terminal velocity of an object go to

probability for j is 1/4

while

a is 1/6

table 3 represents a direct variation function. : )

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.
