Question

Find the value of tan square 30 + 4 sin square 45 + 1 by 3

Answer 1

Answer:

Step-by-step explanation:

tan 30 = 1/√3

Sin 45 = 1/√2

=> Tan square 30 + 4 sin square 45 + 1/3

=(1/√3) square + 4 +× (1/√2) square + 1/3

= 1/3 + 4 × 1/2 + 1/3

=2/3 + 2

=8/3

Answer 2

Answer:

8/3

Step-by-step explanation:

tan^2 30+4sin^2 45 + (1/3)

tan30=1/√3. sin45=1/√2

so

=(1/√3)^2+4(1/√2)^2+(1/3)

=(1/3)+(4/2)+(1/3)

=(1/3)+2+(1/3)

=(1/3)+(6/3)+(1/3)

=(1+6+1)/3

=8/3
