Question

tan square 45 degree +cos square 60 degree + sin square 60 degree
​

Answer 1

Answer:

2

Step-by-step explanation:

tan²45° + cos² 60° + sin² 60°

Using, sin²A+cos²A = 1

= tan² 45° + 1

= 1+1 = 2

Answer 2

=tan^2. 45+cos^2. 60+sin^2. 60

=(1)^2 +(1/2)^2 +(root3/2)^2

=1 + 1/4 + 3/4

=(4 + 1 + 3)/4

=8/4

=2
