Answer:
The value of c is 5 units.
Explanation:
Now by using the pythagorean theorem
Hypotenuse² = Perpendicular² + Base²
As in Δ WYZ.
WZ² = ZY² + WY²
Hypotenuse = WZ = c
Perpendicular = WY = 4 units
Base = ZY = 3 units
Put in the above
c² = 4² + 3²
c² = 16 + 9
c² = 25
c = 5 units
Therefore the value of c is 5 units.
