Answer:
11+✓3/4 . by is for the entire numerator. I hope it's correct
please explain
sorry. I think the ans is 1/2✓3+2
okay... wait for another ans
sin45=1=cos45, sin 60=✓3/2=cos30
by squaring the numerator we get
1-3/4
denomenator we get, ✓3/2+1
4-3/4/✓3+2/2
by solving we get 1/2✓3+2

Step-by-step explanation:
(sin²45°-sin²60°) ÷ (cos30°+cos45°)
(1/√2)²-(√3/2)²÷(√3/2)+(1/√2)
(1/2)-(3/4)÷((√2×√3+2)/2√2)
=(2-3)/4÷√6+2/2√2
-1/4×2√2/(√6+2)
= -√2/2(√6+2)
= -1/√2(√6+2). (2=√2×√2)
= -1/((√12)+2)
= -1/2√3+2
