Question

If tan (2Θ + 25⁰) = cot (3Θ) than the value of theta is (a) 10⁰ (b)11⁰ (c)13⁰ (d)15⁰ (d) 15⁰

Answer 1

Answer:

(c)

Step-by-step explanation:

let phi be (a)

tan(2a+25°)=tan(90°-3a)

2a+25°=90°-3a

5a=65°

a=13°

Answer 2

C= 13; is correct

Tan 2 theta + 25 degree =COT 3 theta

Tan 2 theta + 25 degree =tan90 - 3 theta

2 theta + 25 theta =90 -3 theta.

5 theta = 65

Theta =13
