Answer:
tan Ф = cot(30+2Ф)
cot(90-Ф) = cot(30+2Ф) (→tanФ = cot(90-Ф)
90-Ф = 30 + 2Ф
3Ф = 90-30
3Ф=60
Ф= 20

Answer:
thetha = 20
Step-by-step explanation:
Given,
tanΦ = cot ( 30 + 2Φ )
Since we know,
tan Φ = cot ( 90 - Φ )
Substituting this value of tan Φ
cot ( 90 - Φ ) = cot ( 30 + 2Φ )
Dividing both the sides by cot Φ
( 90 - Φ ) = ( 30 + 2Φ )
90 - 30 = 2Φ + Φ
60 = 3Φ
Dividing both the sides by 3,
3Φ / 3 = 60 / 3
Φ = 20
Hence,
thetha = 20
