Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

Triangle 1

Using Pythagoras theorem (since it is a right angled triangle)

Hypotenuse² = Perpendicular² + Base²

(x) ² = (3) ² + (10) ²

x² = 9 + 100

x² =109

x = √109

x = 10.44

option (c)

------------------------------------

Triangle 2

Using Pythagoras theorem (since it is a right angled triangle)

Hypotenuse² = Perpendicular² + Base²

(11)² = (3.9) ² + (x) ²

121 = 15.21 + x²

x² =121 - 15.21

x² = 105.79

x = √105.79

x = 10.29

option (b)
