Answer 1

Step-by-step explanation:

sin(90-67) cos67 + cos(90-67) sin 67

cos 67 cos 67 + sin 67 sin 67

cos²67+sin²67

Answer 2

Answer:

here is your answer friend

Step-by-step explanation:

we have been given

sin23*cos67 + cos23*sin67

here

sin23*sin(90-67) + cos23*cos(90-67)       [ bcoz ; sina = cos(90-a)

                                                                        cos a = sin(90-a)]

= $sin^{2}$23 + $cos^{2}$23 = 1          [ bcoz  $sin^{2}$a +  $cos^{2}$a= 1]
