describe a simulation that you could use to estimate the probability of guessing answers and scoring 70% on a multiple choice test that has 10 questions Each of which has 5 answer ​

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

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.
