Question

Plz help Find AD……..

Answer 1

AD = 65

Explanation:

Using right triangle ABE

Applying Pythagoras' identity

AB² + BE² = AE²

30² + BE² = 34²

900 + BE² = 1156 ( subtract 900 from both sides )

BE² = 256 ( take square root of both sides )

BE =
`√(256)` = 16

Note that CD = BE = 16

Using the right triangle ACD

Applying Pythagoras' identity

AD² = AC² + CD² = 63² + 16² = 3969 + 256 = 4225 ( take square root of both sides )

AD =
`√(4225)` = 65
