Answer:
d.
Step-by-step explanation:
Since it's an isosceles triangle, WX=WZ= 2n-5
Perimeter = n + (2n-5) + (2n-5)
= 5n - 10
The Perimeter is given to be 20
5n - 10 = 20
5n = 30
n = 6
Answer:
C
Step-by-step explanation:
step 1
Subtract 14 from 50
50-14=36
so

If you solve for p

the answer is the second option
Step-by-step explanation:








Answer:
XZ = XY+ YZ
8.9=5.5+2c
2c= 8.9-5.5
2c=3.4
c=1.7
YZ = 2c=3.4
