Step-by-step explanation:
4×10×2=80
20×10×1=200
20×8×1=160
20×10×1=200
2×20×1=40
10×2×2=40
80+200+160+200+40+40=720
14.4
Step-by-step explanation:
6/10 = x/24
72 = 5x
x = 14.4
Answer:
x = 60
Step-by-step explanation:
By applying mean ratio theorem in the given right triangles ΔABC and ΔBDC,
BD² = AD × DC
BD² = 36 × 64
BD =
BD = 48
By applying Pythagoras theorem in right triangle ΔADB,
AB² = AD² + BD²
x² = (48)² + (36)²
x² = 3600
x = 60
