Question

sin²30 + sin²45° + sin²60°​

Answer 1

Answer:

sin^2 30+sin^2 45+sin^2 60

(1/2)^2+(1/√2)^2+(√3/2)^2

1/4+1/2+3/4

1+2+4/4

7/4

Answer 2

Answer:

3/2

Step-by-step explanation:

Sin²30°+sin²45°+sin²60.

WKT

Sin30°= ½

sin45°= ¹/√2

sin60°= √3/2

(1/2)² + (1/√2)² + (√3/2)²

1/4 + 1/2 + 3/4

(1+2+3)/4

3/2
