Answer:
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangles,
(Hypotenuse)² = (leg 1)² + (leg 2)²
a). (123.1)² = x² + (48.7)²
x² = 15153.61 - 2371.69
x² = 12781.92
x = 113.06 cm
b). (117)² = (82)² + x²
x² = 13689 - 6724
x = 83.46 mm
C). (117)² = t² + (10.3)²
t² = 13689 - 106.09
t² = 13582.91
t = 116.55 cm
