Math 7. grade 7.
can anyone me answer this ?

a bunch of students decided to have a movie night. they decided that the movie night will last 4 hours. each movie takes 1.75 hours and 0.5 hours for chatting together between the movies start.

m = amount of movies watched

equation to you figure out this which one of the following choices?

1.75 m = 3.5
1.75 + m = 3.5
m/1.75 = 3.5
m/3.5 = 1.75

so how many full movies can they show? which of the following choices?

3 movies
2.2 movies
2 movies
4 movies

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.
