Camille rolls two number cubes together and records the sum. If she does this 180 times, how many times should she expect the sum to be 7?

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

answer: the answer for that is 22/3

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
