A jar contains 6 red marbles numbered 1 to 6 and 12 blue marbles numbered 1 to 12. A marble is drawn at random from the jar. Find the probability of the given event. (a) The marble is red
Your answer is :

(b) The marble is odd-numbered
Your answer is :

(c) The marble is red or odd-numbered
Your answer is :

(d) The marble is blue and even-numbered
Your answer is :

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

-1/3(x+1)^5

i’m pretty sure this is correct

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.
