) Find the value of :(cos 0 0 + sin 45 + sin 30 °) (sin 90° - cos 45

1.	) Find the value of :(cos 0 0 + sin 45 + sin 30 °) (sin 90° - cos 45 + cos 60)
Answer» Answer: (COS 0 + sin45+sin30)(sin90 - cos 45 + cos 60) (1+1/√2+1/2)(1-1/√2+1/2) = 7/2 therefore (cos 0+SIN 45+sin 30 )(sin 90 - cos 45 + cos 60)= 7/2 Step-by-step EXPLANATION:

) Find the value of :(cos 0 0 + sin 45 + sin 30 °) (sin 90° - cos 45 + cos 60)

Answer»

Answer:

(COS 0 + sin45+sin30)(sin90 - cos 45 + cos 60)

(1+1/√2+1/2)(1-1/√2+1/2)

= 7/2

therefore (cos 0+SIN 45+sin 30 )(sin 90 - cos 45 + cos 60)= 7/2
