D = M/V
D= 21/7
D = 3 g/cm3
Answer:
The length of third side is: 6.3
Step-by-step explanation:
Given triangle is a right triangle where
Base = ?
Perpendicular = 5
Hypotenuse = 8
Let x be the base
As it is a right-angled triangle, Pythagoras theorem can be used to find the third side

Putting the known values

Taking square root on both sides

Rounding off to the nearest 10th
Base = 6.3
Hence,
The length of third side is: 6.3
