Answer:

The answer to your question is AC = 9.9

Step-by-step explanation:

To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.

cos α = $\frac{adjacent side}{hypotenuse}$

Solve for hypotenuse

$hypotenuse = \frac{adjacent side}{cos\alpha }$

Substitution

hypotenuse = $\frac{9}{cos 24}$

Simplification and result

hypotenuse = 9.85

How to solve these two problems ？

puteri [66]

8) $\theta$ is -0.896 radians

9) length of arc is 41.91 cm

Solution:

Given that,

$tan\ \theta = \frac{-5}{4}$

$\theta$ is in quadrant 4

To find: $\theta$

From given,

$tan\ \theta = \frac{-5}{4}\\\\\theta = tan^{-1} \frac{-5}{4}\\\\\theta = tan^{-1} (-1.25)\\\\\theta = -51.34$

Thus value of $\theta$ is -51.34 degrees

Convert degrees to radians

$-51.34\ degree = -51.34 \times \frac{ \pi }{180}\ radian\\\\-51.34\ degree = -0.896\ radian$

Thus $\theta$ is -0.896 radians

From given,

radius = 15.4 cm

$\theta = \frac{13 \pi }{15}$

<em><u>The length of arc when angle in radians is:</u></em>

$arc\ length = r \times \theta\\\\arc\ length = 15.4 \times \frac{ 13 \pi }{15}\\\\arc\ length = 15.4 \times 2.721\\\\arc\ length = 41.91$

Thus length of arc is 41.91 cm

Which equation is in standard form and represents a line with slope –1 through the point (–3, 5)?

likoan [24]

I hope this helps you

slope = -1 x'= -3 y'=5

slope. (x'-x)=y'-y

-1. (-3-x)=5-y

3+x=5-y

y=2-x

Amar wants to make lemonade for a birthday party. He wants to mix 12 tablespoons of sugar in water. He only has a teaspoon which

o-na [289]

Answer:48

Step-by-step explanation:

Given

Amar wants 12 tablespoons of sugar in water.

Amar has teaspoon whose four times is equivalent to 1 tablespoon

i.e. $4\ \text{teaspoon}\equiv 1\ \text{tablespoon}$

therefore

$12 tablespoon is 4\times 12$

$\Rightarrow 4\times 12$

$\Rightarrow 48\ \text{teaspoons}$

So, amar need to add $48\ \text{teaspoons}$ for lemonade
