Answers:
- x = 3
- CD = 21
- DE = 16
- CE = 21
=============================================================
Explanation:
The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.
CE = CD
16x-27 = 4x+9
16x-4x = 9+27
12x = 36
x = 36/12
x = 3
This x value then leads to the following:
- CD = 4x+9 = 4*3+9 = 12+9 = 21
- DE = 7x-5 = 7*3-5 = 21-5 = 16
- CE = 16x-27 = 16*3-27 = 48-27 = 21
We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.

Step-by-step explanation:
Answer:
5/8
Step-by-step explanation:
Simplify the following:
35/56
The gcd of 35 and 56 is 7, so 35/56 = (7×5)/(7×8) = 7/7×5/8 = 5/8:
