Question

4) Value of sin 30° +cos 60° is
A) 1/2
B) 3/2
C) 1/4
D) 1
​

Answer 1

Answer:

1

Step-by-step explanation:

value of sin 30 is 1/2

value of cos 60 is 1/2

sin 30+ cos 60= 1/2+1/2= 1

Answer 2

Answer:

d . 1 is the correct answer

Step-by-step explanation:

sin 0° = √(0/4) = 0

sin 30° = √(1/4) = ½

sin 45° = √(2/4) = 1/√2

sin 60° = √3/4 = √3/2

cos 90° = √(4/4) = 1

Cos Values

cos 0° = √(4/4) = 1

cos 30° = √(3/4) = √3/2

cos 45° = √(2/4) = 1/√2

cos 60° = √(1/4) = 1/2

cos 90° = √(0/4) = 0

Substitute the value of sin 30o and cos 60o value we get

sin 30o + cos 60o

= 1/2 + 1/2

= 1
