Question

[sin30 + cos30) - [Sin60 + cos60)
a.–1
b) o
c)1
d) 2​

Answer 1

Step-by-step explanation:

(sin30+cos30) - (sin60+cos60)

sin30 = 1/2

sin60= √3/2

cos30= √3/2

cos60= 1/2

=> (1/2+√3/2) - (√3/2+1/2)

=> 1+√3/2-√3+1/2

=> 1+1+√3-√3/2

=> 2/2

=>1

The correct answer is c) 1

Answer 2

Answer:

answer is 0

Step-by-step explanation:

sin30 = cos60 = 1/2

sin60 = cos30 = √3/2

then, sin30+cos30-sin60-cos60 = 0
