Answer:
x = 25
40 (√3 - 1)
Step-by-step explanation:
3Tan²(2x - 20)° = 1
=> Tan²(2x - 20)° = 1/3
Taking square root both sides
=> Tan(2x - 20)° = 1/√3
Tan 30° = 1/√3
=> 2x - 20 = 30
=> x = 25
2
Tan 60 = AC/BC = AC/40 =>
√3 = AC/40 => AC = 40√3
Tan45 = DC/BC
=> 1 = DC/40
=> DC = 40
AD = AC - DC = 40√3 - 40
= 40 (√3 - 1)
