Jawaban:

15√3

Penjelasan dengan langkah-langkah:

Segitiga ABC

a = 24 = BC

b = 5 + x = AB

c = 10 + 16 = 26 = AC

rumus pythagoras

a²+b² = c²

24² + (5+x)² = 26²

576 + (5+x)² = 676

(5+x)² = 676 - 576

(5+x)² = 100

5 + x = √100

5 + x = 10

x = 10 - 5

x = 5 = AD

Segitiga ADE

a = AD = 5

b = DE = x

c = AE = 10

rumus pythagoras

a²+b² = c²

5² + x² = 10²

25 + x² = 100

x² = 100-25

x² = 75

x = √75 = √25.3

= 5 √3 = DE

Keliling segitiga ADE

AD + DE + AE

= 5 + 5√3 + 10

= 15 + 5√3
