Question

5sin theta =13 find cos theta​

Answer 1

Answer:

cos theta is equal to 12/5

Step-by-step explanation:

we have given that

5 sin theta =13

sin theta =13/5

perpendicular /base= 13/5

using pythagaurus theorem

h square = p square plus b square

h square minus p square = b square

b is equal to 12

cos theta =. base / hypotnese

cos theta = 12/5
