Question

Find theta if tan 3 theta= Sin45 Cos45 +Sin30​

Answer 1

here's your answer above

Answer 2

Answer:

Theta = 15°

Step-by-step explanation:

let theta = x

According to question,

Tan3x = sin45cos45 + sin30

Tan3x = 1÷√2 × 1÷√2 + 1÷2

Tan3x = 1÷2 + 1÷2

Tan3x = 1 = Tan45

Therefore,

Tan45 = Tan 3x

By comparing,

3x = 45

x = 15

Therefore theta = 15°
