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
