Answer 2

Since tower stands for angle 90°.

→ tan 60° = (1.6 + x)/Base

→ √3 = (1.6 + x)/Base

→ Base = (1.6+ x)/√3

→ tan 45° = Pedestal/Base

→ 1 = x/Base

→ Base = x

→ x = (1.6 + x)/√3

→ √3x = 1.6 + x

→ x(√3 - 1) = 1.6

→ x = 1.6/(√3 - 1) × (√3 + 1)/(√3 + 1)

→ x = 1.6(√3 + 1)/2

→ x = 0.8 × (1.732 + 1)

→ x = 1.639 m

Hence height of pedestal is 1639 cm.
