Bonnie is four years older than Clyde.

Doss [256]

Answer:

Bonnie's age is 18

Step-by-step explanation:

Let

x ----> Bonnie's age

y ---> Clyde's age

we know that

$x=y+4$ ----> equation A

$x-10=2(y-10)$

$x-10=2y-20$

$x=2y-20+10$

$x=2y-10$ ----> equation B

substitute equation A in equation B

$y+4=2y-10$

Solve for y

$2y-y=4+10$

$y=14$

Find the value of x

$x=14+4=18$

therefore

Bonnie's age is 18

Clyde's age is 14

In a right triangle, CosA=0.352 and SinA=0.936 What is the approximate value of tanA?

mr_godi [17]

$\tan A=\frac{\sin A}{\cos A}$

Proof: $\sin\div\cos=\frac{o}h\div\frac{a}h=\frac{o}h\times\frac{h}a=\frac{oh}{ha}=\frac{o}a=\tan$

$\cos A=0.352,\ \sin A=0.936$

$\tan A=\frac{0.936}{0.352}$

$\boxed{\tan A=2.65\overline{90}}$ (round as needed)
