Question

find the altitude of a triangle if it hypotenuse is 25cm and one side is 15cm.​

Answer 1

${al}^{2} = {h}^{2} - {b}^{2}$

$= \sqrt{ {25}^{2} - {15}^{2} } = \sqrt{625 - 225} = \sqrt{400} = 20$

Answer 2

Aɴsᴡᴇʀ⤵️

ʜʏᴘᴏᴛᴇɴᴜsᴇ = 25ᴄᴍ

Oɴᴇ sɪᴅᴇ (ʙᴀsᴇ) = 15ᴄᴍ

Fɪɴᴅ Aʟᴛɪᴛᴜᴅᴇ ᴏғ ᴀ ᴛʀɪᴀɴɢʟᴇ.

(ᴀʟᴛɪᴛᴜᴅᴇ)^2 = (ʜʏᴘᴏᴛᴇɴᴜsᴇ)^2 - (ʙᴀsᴇ)^2

(Aʟᴛɪᴛᴜᴅᴇ)^2 = (25)^2 - (15)^2

(ᴀʟᴛɪᴛᴜᴅᴇ)^2 = 625 - 225

(ᴀʟᴛɪᴛᴜᴅᴇ)^2 = 400

Aʟᴛɪᴛᴜᴅᴇ = ✓400

ᴀʟᴛɪᴛᴜᴅᴇ = 20ᴄᴍ

Aʟʟ ᴛʜᴇ ʙᴇsᴛ :)
