Question

(sin60°+sin45°-sin90°)(cos30°+cos45°+cos0°) EVALUATE IT.
PLEASE ​

Answer 1

Step-by-step explanation:

(root 3/2 + 1 /Root 2 - 1 )( root 3/2 +1 / root 2 + 1)

= ( root 3/ 2 + 1 / root 2)2 - 1

={( root 3+ root 2 )2 / 4} -1

=( 3+2 root 2) / 4

Answer 2

Step-by-step explanation:

(sin60°+sin45°-sin90°)(cos30°+cos45°+cos0°)

=(√3/2+1/√2-1)(√3/2+1/√2+1)

=(√3+√2-2)(√3+√2+2)

2. 2

=(√3+√2)²-2²

4

=3+2+2√6-4

4

= 1+2√6
