Step-by-step explanation:
Answer:
AE = 7.5
Step-by-step explanation:
Since <BAC =
, then;
<BAD = <DAE = <CAE =
(complementary angles)
From ΔABC, applying the Pythagoras theorem to determine the length of side AC;
=
+ 
=
+ 
100 =
+ 25
= 100 - 25
= 75
AC = 
Applying trigonometric function to ΔCAE,
Cos
= 
AE =
× Cos 
= 7.5
Therefore, AE = 7.5

Answer:
x<2
Step-by-step explanation:
The first (and most typical) way to find distance of two points is by using the distance formula.

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
