Answer: 1
Step-by-step explanation:
sin^2 30°= (1/2)^2 = 1/4
cos^2 30°= (/2)^2 = 3/4
So,
sin^2 30° - cos ^2 30°\ sin^2 30°+cos ^2 30°
= 1/4 - 3/4 / 1/4 - 3/4
= 1/1
=1
Hope it helps...

Answer:
sin²30°-cos²30°/sin²30°+ cos30°
Step-by-step explanation:
(1/2)²-(√3/2)²/(1/2)²+√3/2
1/4-3/4/1/4+√3/2
1/4-3-√3/2
1-12-2√3/4
