Step-by-step explanation:

z=99°

15x + 36 + 99=180

15x+135=180

15x=180-135

15x=45

divide by 15

x=3

Cos(a) 63/65 to find sin(a) and tan(a)
Semenov [28]

Answer:

\huge\boxed{\sin\alpha=-\dfrac{16}{65},\ \tan\alpha=-\dfrac{16}{63}}\\\\or\\\\\huge\boxed{\sin\alpha=\dfrac{16}{65},\ \tan\alpha=\dfrac{16}{63}}

Step-by-step explanation:

\cos\alpha=\dfrac{63}{65}\\\\\text{use}\ \sin^2\alpha+\cos^2\alpha=1\\\\\sin^2\alpha+\left(\dfrac{63}{65}\right)^2=1\\\\\sin^2\alpha+\dfrac{3969}{4225}=1\qquad\text{subtract}\ \dfrac{3969}{4225}\ \text{from both sides}\\\\\sin^2\alpha=\dfrac{4225}{4225}-\dfrac{3969}{4225}\\\\\sin^2\alpha=\dfrac{256}{4225}\to\sin\alpha=\pm\sqrt{\dfrac{256}{4225}}\\\\\sin\alpha=\pm\dfrac{\sqrt{256}}{\sqrt{4225}}\\\\\sin\alpha=\pm\dfrac{16}{65}

\text{use}\ \tan\alpha=\dfrac{\sin\alpha}{\cos\alpha}\\\\\text{substitute:}\\\\\tan\alpha=\dfrac{\pm\frac{16}{65}}{\frac{63}{65}}=\pm\dfrac{16}{65}\cdot\dfrac{65}{63}=\pm\dfrac{16}{63}

A sightseeing boat charges $5 for children and $8 for adults. on its first trop of the day, it collected $439 for 71 paying pass
Mrac [35]

if 71 paying passengers are all children, they should pay 5* 71= $355 in total.

$439 is paid so adults pay $439-$355 = $84 more than money paid by same number of children.

each adult pays $8-$5=$3 more than each child

so there are $84/$3= 28adults

and 71-28= 43 children
