We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
I believe the answer would be 6/25 simplified. 12/50 would be the original answer
Answer:
A) JK and LM will be parallel to each other.
Step-by-step explanation:
On reflection on line the x co-ordinate changes with y co-ordinate and y co-ordinate changes with x co-ordinate
Points on line EF
On reflection of this line on the new points we get for line JK are
Points on line GH
On reflection on y=x line the new points we get for line LM are
Slope of line JK
Slope of line LM
For two line to be parallel, their slopes will be same.
Since slopes of lines JK and LM are same therefore we can say that these are parallel to each other.
Answer:
B
Step-by-step explanation:
The answer would be a. Yes, the student’s answer is
reasonable.
In the problem, it states that Cindy rode her bike for an
hour and ran for an hour. Without the
presence of the comma between rode her bike for an hour, and ran for an hour,
this just means that Cindy only rode her bike and ran it for an hour.
The sentence can be written as Cindy rode her bike and ran
for an hour. So, this gives an answer
that Cindy only exercise for an hour.
