Answer:
Measure of bc is 5√3
Explanation:
Given right angled triangle ABC
ac = 5
ab = 10
We know that according to Pythagoras Theorem
Perpendicular² + Base² = Hypotenuse²
then ac² + bc² = ab²
i.e. 5²+ bc² = 10²
25 + bc² =100
subtracting both sides by 25
25 + bc² -25 = 100 -25
bc² = 75
bc =5√3
Thus the measure of side bc is 5√3
