HELP!! What is the approximate measure of angle x in the triangle shown?

Alex Ar [27]

<h3>Answer: D) 130.5 degrees</h3>

=================================================

Work Shown:

$c^2 = a^2 + b^2 - 2*a*b*\cos(C)\\\\10^2 = 5^2 + 6^2 - 2*5*6*\cos(x)\\\\100 = 25 + 36 - 60*\cos(x)\\\\100 = 61 - 60*\cos(x)\\\\100 - 61 = - 60*\cos(x)\\\\39 = - 60*\cos(x)\\\\\cos(x) = \frac{39}{-60}\\\\\cos(x) = -0.65\\\\x = \arccos(-0.65)\\\\x \approx 130.5416\\\\x \approx 130.5\\\\$

Note: I used the law of cosines. Make sure your calculator is in degree mode.

Which is greater, -9/20 or -0.5?

Natali5045456 [20]

Answer and Step-by-step explanation:

If we put $-\frac{9}{20}$ into decimal form, we get -0.45.

-0.45 is greater than -0.5, so,

<u></u> $-\frac{9}{20}$ <u> is greater than -0.5.</u>

Given you or a person holding a kite string 100 feet long write and draw what the height or altitude the kite is off the ground

Salsk061 [2.6K]

Answer: $75.47\ ft$

Step-by-step explanation:

Given

String of the kite is $l=100\ ft$

Angle of elevation $\theta=49^{\circ}$

suppose altitude of the kite is h

from the figure, we can write

$\Rightarrow \sin 49^{\circ}=\dfrac{h}{100}\\\\\Rightarrow h=100\sin 49^{\circ}\\\\\Rightarrow h=75.47\ ft$

Thus, the altitude of the kite is $75.47\ ft$
