Question

(3) Urgent.. please help me.... Please do not write nonsense as an answer to get points because I WILL report you..please? Answer all if you can bc it is a lot of points.

Answer 1

Well you know that

sin X=Op/Hip

cos X=Ady/Hip

tan X=Op/Ady

so the first one

`sin(A)=(9)/(√(90) ) =(3√(10) )/(10)`

`cos(A)=(3)/(√(90) ) =(√(10) )/(10)`

`tan(A)=(9)/(3) =3`

the second

`sin(C)=(5)/(7)`

the third

`cos(X)=(18)/(9√(5) ) =(2√(5) )/(5)`

the fourth

`sin(B)=(8)/(10) =(4)/(5)`

the fifth

`tan(34)=(x)/(29)`

`x=tan(34)*29=19.56` aprox.
