Question

1. Evaluate the following:
(i) sin 60° cos 30° + sin 30° cos 60°​

Answer 1

step-by-step explanation:-

sin60°=✓3/2,sin30°=1/2

cos30°=✓3/2,cos 60°=1/2

sin60°cos30°+sin30°cos60°

✓3/2.✓3/2+1/2.1/2

=3/4+1/4=4/4

=1

2nd method:-

we know that sin(A+B)=sinAcosB+sinBcosA

the given is also in this form

sin(60+30)=sin90°

=1

Answer 2

Answer:

1 is the answer of your question

Step-by-step explanation:

sin 60⁰ = √3/2

cos 30⁰=√3/2

sin30⁰ = 1/2

cos 60⁰= 1/2
