Question

write the value of sin²30°+cos²60

Answer 1

Answer: $\frac{1}{2}$

sin 30°=$\frac{1}{2}$

cos 60°=$\frac{1}{2}$

sin² 30°=$\frac{1}{4}$

cos² 60°=$\frac{1}{4}$

The answer is $\frac{1}{2}$

Answer 2

Answer:

1/2

Step-by-step explanation:

sin²30° + cos²60°

∵ sin 30° = 1/2 and cos 60°= 1/2

= (sin 30°)² + (cos 60°)²

= (1/2)² + (1/2)²

= 1/4 + 1/4

= 2/4

= 1/2
