  1. 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 🙂

  2. [tex] {al}^{2} = {h}^{2} – {b}^{2} [/tex]

    [tex] = \sqrt{ {25}^{2} – {15}^{2} } = \sqrt{625 – 225} = \sqrt{400} = 20[/tex]
