Question

in trigonometric eqations, if sin teta =12/13 and 'teta' is acute, find cos teta and tan teta

Answer 1

Answer:

cos theta = 5/13 and tan theta =12/5

Step-by-step explanation:

cos theta = b/h

tan theta =p/b

here

sin theta = 12/13 = p/h

so b=5( by Pythagoras theorm),p=12,h=13

thus

cos theta = 5/13

tan theta = 12/5
