Question

Can you please help me do this and explain how you did it so I can look at it for references thanks so much (:

Answer 1

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
