Question

1. State Pythagoras property and using it find BC in the figure.
​

Answer 1

$\huge \bold{Answer:}$

⚘Formula used:

• Hypo= √(base)²+(height)²
• Height= √(hypo)²-(base)²
• Base=√(hypo)²-(height)²

⚘Solution:

Given,

Base= 7cm

Hypo= 25cm

Now,

$➙Hᴇɪɢʜᴛ= \sqrt{ ({ʜʏᴘᴏ} )^{2} - (ʙᴀsᴇ {)}^{2} }$

$➙Hᴇɪɢʜᴛ= \sqrt{ ({25} )^{2} - (7 {)}^{2} }$

$➙Hᴇɪɢʜᴛ= \sqrt{625 - 49}$

$➙Hᴇɪɢʜᴛ= \sqrt{576}$

$➙Hᴇɪɢʜᴛ=24cm$

Therefore, The length of BC is 24 cm.
