Answer 1

Answer:

bd:14

cd:16

Step-by-step explanation:

we we will use Pythagoras theorem in this sum and find BD with this BD is value we will use again Pythagoras theorem in triangle B C D and find CB

Answer 2

Answer:

Two poles AB and CD stand vertically on the flat ground . Find BD and CD.

Step-by-step explanation:

BD² = AD² +AB²

BD² = (15 m)² + (9 m)²

BD² =√225 m - 81 m

BD² = √144 m

BD = 12 m

CD² = BC² - BD²

CD² = (20 m)² - (12 m)²

CD² = √400 m - 144m

CD = 16 m

The value of BD = 12 m and CD = 16 m
