Answer:
a) 16.25 centimeters
b) 6.8 centimeters
Step-by-step explanation:
We can set up a proportion for both of these problems.
a) Look at the longest side of each triangle. We can set up a fraction: 7.2/18. We can also set up a fraction for XZ and PR:
6.5/x
x represents the length you're trying to find.
Since the triangles are similar, we have an equation:
7.2/18=6.5/x
Cross multiply
16.25
XZ is 16.25 centimeters long.
b)
We can do same thing:
7.2/18=x/17
Cross multiply
6.8
QR is 6.8 centimeters long.
Hope this helps!
Well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min
Apply the "FOIL" method here. (m+1)(m+1) = m^2 + 1m + 1m + 1, or m^2 + 2m + 1.
Answer:
I think Leslie Is 20
Step-by-step explanation:
<u>Given</u>:
The measures of the alternate exterior angles are (180 - x)° and x°
We need to determine the value x that makes m ║ n
<u>Value of x:</u>
We know that the measures of alternate exterior angles are equal.
Thus, we have;
Adding both sides of the equation by x, we have;
Simplifying, we get;
Dividing both sides of the equation by 2, we have;
Thus, the value of x is 90.
Hence, the value x = 90 makes the alternate exterior angles congruent and hence the line m is parallel to n.
