Question

cos^2 60°+sin^2 30°+tan^2 60°/2​

Answer 1

Answer:

1.75

Step-by-step explanation:

 cos²60° + sin²30°+tan²60°/2​

= $\frac{\frac{1}{2}^{2} +\frac{1}{2}^{2}+(\sqrt{3} )^2 }{2}$

=$\frac{\frac{1}{4} +\frac{1}{4}+3 }{2}$

= $\frac{\frac{2}{4}+3 }{2}$

= $\frac{\frac{1}{2}+3 }{2}$

= $\frac{\frac{1}{2}+\frac{6}{2} }{2}$

=$\frac{\frac{7}{2} }{2}$

=$\frac{7}{4}$

= 1.75
