Answer:
x=4
Step-by-step explanation:
For E to be the midpoint of DF, it needs to divide DF in 2 equal segments, DE and EF. If E is the midpoint of DF, then DE and EF are equal, so the reason is that the expressions for DE and EF are equal. The reason is:
One way of estimating is to Round the numbers to the nearest whole number.

Answer:
4.48
Step-by-step explanation:
Answer:
11° and 79°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then the other angle = x + 68 , hence
x + x + 68 = 90
2x + 68 = 90 ( subtract 68 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°
As a check : 11 + 79 = 90
