Question

(i) Sin 60°* Cos 30° +Sin30°*Cos60°​

Answer 1

Answer:

Answer is 1

Step-by-step explanation:

apply the formula sin(90-¢)= cos¢

Answer 2

Answer:

2

Step-by-step explanation:

$\frac{\sqrt{3}}{2} *\frac{\sqrt{3}}{2}+\frac{1}{2} *\frac{1}{2}$                             [sin30=1/2,sin60=$\frac{\sqrt{3}}{2}$     ;cos30=$\frac{\sqrt{3} }{2}$ ,cos60=1/2]

$\frac{3}{2} +\frac{1}{2}$ = $4/2$=2
