I need some help with this

Ivenika [448]

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

$sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}$

AKA SohCahToa.

To find the height, we will use sine.

$sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14$

To find the length we will use cosine.

$cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6$

NEED HELP ASAP!! <br><br> Use the function below to find F(3)

kvv77 [185]

It’s gonna be 1/125.

Since it’s F(3), you need to plug the 3 into the x. Then expand it into 1/5 times 1/5 times 1/5, which gets you 1/125

Find the x value of x. If necessary round to the nearest tenth. A=49sq.in.

grigory [225]

Answer:

$9.9 ~in$ ✔︎

Step-by-step explanation:

$A=1/2 ~ base * height$

$49=1/2(x)(c)$

$98=x^2$

$x=\sqrt{98}$

$x=7\sqrt{2}$

$x=9.9$
