I don’t understand the question pls help
Alex_Xolod [135]

Answer:

AC = 15.6

Step-by-step explanation:

AC = AE + EC

By he Pythagorean theorem,

A² + B² = C²

12² + 5² = AE²

144 + 25 = AE²

AE = √169

AE = 13

Find Angle AED

tan Angle AED = 12/5

Angle AED = tan-1 (12/5)

= 67.38°

Angle AED = Angle BEC

tan (67.38°) = BC/1

BC = 2.4

1² + 2.4² = EC²

6.76 = EC²

EC = √6.76

EC = 2.6

AC = 13 + 2.6

AC = 15.6
