Question

Pls help me with trig i would rlly appreciate !! 22 only

Answer 1

I think none of these answers are correct

Answer 2

Explanation:

given,

tan thita =8/9

or,tan thita=p/b

now, h=

`\sqrt{p {}^(2) + b {}^(2) }`

`= \sqrt{8 {}^(2) + 9 {}^(2) }`

`= √(145)`

therefore, h=

`√(145)`

now, cos thita =b/h

so, cos thita =

`9 / √(145)`

`= 9 √(145) / √(145)`

......ans........

hope its helpful
