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
