Answer:
A) 196 = 100 + b ²
Step-by-step explanation:
Using the pythagoras theorm;
c² = a² + b²
c = 14 a = 10
substituting the value into the above formula;
14² = 10² + b²
196 = 100 + b²
subtract 100 from both-side of the equation
196- 100 = b²
96 = b²
Take the square root of both-side of the equation to get the value of b
√96 = √b²
9.78 = b
b≈9.8
Therefore usikng the pythagoras theorm to find the missing side, the equation that can be used to solve for b is 196 = 100 + b ²
