If a right angled-triangle has sides A,B,C where A = 4 and B = 3 what is the value of side C?

This problem can be solved using Pythagoras Theorem equation: A² + B²= C² (see diagram for explanation)
Substitute the numbers given in the question into this equation:(4)²+ (3)² = C²Expand out the brackets:16 + 9 = C²25 = C²To find the final value of C do square root.
C= 5
