Question

if sin thetra=11/61 then find cos thetra and tan thetra​

Answer 1

Step-by-step explanation:

given: sin thetra=11/61 , perpendicular =11

, hypotenuse=61

find: cos thetra = ?

tan thetra=?

sol: h²=P²-B²( by pythagoras theorem)

(61)²=(11)² -B²

3721= 121-B²

B²=3721-121

B²=3600

B= √3600

B=60

cos thetra =Base/Hypotenuse

cos thetra = 60/61

tan thetra=perpendicular/Base

tan thetra=11/60
