Question

Find the value of sin25 upon cos65 + tan23 upon cot67

Answer 1

Answer:

sin theta = cos(90-theta)

tan theta= cot (90-theta)

sin25/sin 25+ tan 23/ tan 23

1+1= 2

the answer is 2

Answer 2

Answer:

2

Step-by-step explanation:

$= \frac{ \sin(25) }{ \cos(65) } + \frac{ \tan(23) }{ \cot(67) } \\ = \frac{ \sin(90 - 25) }{ \cos(65) } + \frac{ \tan(90 - 23) }{ \cot(67) } \\ = \frac{ \cos(65) }{ \cos(65) } + \frac{ \cot(67) }{ \cot(67) } \\ = 1 + 1 \\ = 2$
