Question

calculate the lengths of
(i) BD,
(ii) BC.​

Answer 1

Step-by-step explanation:

BD²=(10)²-(6)²

BD= 8

BC²= (8)² + (15)²

BC = 16.8

Answer 2

Answer: BD = 8cm

BC = 17cm

Step-by-step explanation:

Since ABD is a right triangle

10^2 = 6^2 - x^2

100 = 36 - x^2

x^2 =64

x = 8

So BD = 8cm

BC^2 = 15^2 + 8^2

BC^2 = 225 + 64

BC^2 = 289

BC = 17cm
