Answer 1

Answer:

okk i will try these

Answer 2

Answer:

4 . 3 cm

Step-by-step explanation:

At First Draw Perpendicular along Any side of ∆ ;

Then , That side will bisect into two

i.e each half measures 2.5 cm

Now , According to Pythagoras Theorem : -

( Apply on any Half of ∆ )

( Height of ∆ ) ^ 2 + ( 2.5 ) ^ 2 = ( 5 ) ^2

( Height of ∆ ) ^ 2 = 25 - 6.25 = 18.75

Therefore ; Height of ∆ = ~ 4.3 cm .
