Answer:
The value of missing side is 32 unit .
Step-by-step explanation:
Given as :
The measure of hypotenuse = h = 60 unit
The other side = base = b = 68 unit
Let The missing side = x unit
Now, <u>From Pythagoras Theorem</u>
Hypotenuse² = Perpendicular² + Base²
And From figure
Or, p² = b² - h²
So, p² = 68² - 60²
Or, x² = 4624 - 3600
Or, x² = 1024
∴ x =
I.e x = 32 unit
So,The missing side = x = 32 unit
Hence The value of missing side is 32 unit . Answer
