Answer:
as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition
such as
corresponding angles, AB//CD ,
alternate angles, AB//CD ,
interior angles, AB//CD
In my figure, a+b is always equal to 180degree if the X line is straight
a+b=180
imagine there is Y line which is parallel to the X line
c+d=180
a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)
then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
Answer:
If this is the only information you have, the answer would be somewhere around 125. Usually, you would find the third quartile by first finding the median. Then find the median of all of the numbers between the median and the largest number, which is the third quartile.
Step-by-step explanation:
3/5 divied by 1 5/9
3/5 times 9/14 =27/70
It already is simplified, youre answer is 27/70
Answer:
Pam is 51.
Jan is 48.
Step-by-step explanation:
Pam is 3 years older than Jan so her age is x + 3 where x is Jan's age. When we add Pam's age and Jan's age, the sum equals 99.
So x + x+3 = 99. Solve for x.
2x+3 = 99
2x=96
x= 48
So Jan is 48 years old. This means Pam is 51.
