Step-by-step explanation:
3 cos 80° cosec 10° + 2 sin 59° sec 31°
• cosec theta = 1 / sin theta
• sec theta = 1 / cos theta
therefore, 3 [ cos 80 / sin 10 ] + 2 [ sin 59 / cos 31 ]
• sin ( 90- theta) = cos theta
• cos ( 90- theta) = sin theta
3 [ cos 80 / sin (90 - 80)] + 2 [ sin 59 / cos (90 - 59)]
3 [ cos 80 / cos 80 ] + 2 [ sin 59 / sin 59 ]
3 (1) + 2 (1) = 5
therefore the answer to this question is 5
