Question

What is the value of A if Tan 3A = Sin 45⁰ Cos 45⁰ + Sin 30⁰? . *

Answer 1

Answer:

Suppose A as x .

Step-by-step explanation:

RHS:

sin45.cos45+sin30

=1|√2.1|√2 + 1|2

= 1|2+1|2

=2|2

=1

now,

tan 3x = 1

but tan 45° = 1

therefore,

tan 3x = tan 45

means 3x = 45

& x=45÷3

hence x= 15
