Rosa wants to go the football game friday night, but her neighbor has asked her to babysit that evening. if rosa chooses to babysit friday night, she will earn $25. if she decides to go to the football game, she will spend $5 on the ticket and likely spend another $5 on snacks at the game. what is the opportunity cost for rosa of choosing to go to the game instead of babysitting?

it should be a.

hope it

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
