72 times square root of 2
The entire length of the line, AE, is 38. We are asked to find the length from point C to point E.
AB and BC are both 5 units in length. The length from point B to point D is 17. So, if we subtract 5 from 17, we get 12.
The length between point C and point D is 12. DE appears to be of the same distance. So, DE is also 12.
12 + 12 = 24
So, CE = 24.
Such an expression is in its Simpliest Form
Step-by-step explanation:
For question no. 3
Since we are aware that measure of the sum of all the three interior angles of a triangle is 180°.

Answer:
C. 6 + 8 would be equivalent to 6-(-8)
