Question

Bantu no 21+22 ya:) hehe

Answer 1

INGAT :
h² = x² + y²
h = hipotenusa
x = sisi horizontal
y = sisi vertikal

21. D
22. ΔAEB ≈ ΔCTB
     T = antara C dan D --=> CT = 6
     EB = AE = BA
      TB  CT      CB
     EB = TB x 18 : 10
     TB = √(CB² - CT²) = √64 = 8
     EB = 8 X 18 : 10 = 72 : 5 = 14,4    ---------=> C
