I would need see what your choices are to give exact answers, but I think the main idea here is to see that angles 1 and 3 are the same, and since the alternate interior angle theorem states parallel lines through a line, or another set of parallel lines, form equal angles on those positions, the lines that form those angles, p and q, must be parallel.
Answer:
Step-by-step explanation:
Point B is 6 units below and 4 units to the right of A, so the slope is ...
slope = (change in y)/(change in x) = -6/4 = -3/2
Point R corresponds to point B, so will be 6 units below and 4 units to the right of point Q.
R = Q + (4, -6) = (2, -4) + (4, -6) = (2+4, -4-6)
R = (6, -10)
<u>Answer:</u>
The correct answer option is
.
<u>Step-by-step explanation:</u>
We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).
Total number of days in a week = ![7](https://tex.z-dn.net/?f=%207%20)
Number of days in weekend = ![2](https://tex.z-dn.net/?f=%202%20)
Probability of being born on weekend = ![\frac { 2 } { 7 }](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B%202%20%7D%20%7B%207%20%7D%20)
P (both parents were born on weekend) =
= 4/49
The formula u should use us 3(bxh divided by 2) then for the smaller triangle just bxh divided by 2 bcuz the other 3 will have the same base and height but the last one doesn't
