Answer:
a=5
Step-by-step explanation:
a^2+b^2=c^2
c^2-b^2=a^2
13^2-12^2=a^2
169-144=a^2
25=a^2
5=a
3.75 as a decimal, 3 &3/4 as a fraction
well frist you might wanna get down the measurments 12 inch equals 1 foot then do step by step and see what it adds up too then you have your !answer!
Step-by-step explanation:
Answer: they are parallel
Step-by-step explanation:
find slope of line m:
Use y2-y1/x2-x1
your m equation --> 9-15/10-3 which makes the slope of m = -6/7
find slope of line n:
Use y2-y1/x2-x1
your n equation --> 3-9/9-2 which makes the slope of n = -6/7
The slopes are the same, therefore line m and line n are parallel.
