Answer:

(D)9 divided by sin 60 degrees

Step-by-step explanation:

From the given figure, using trigonometry

$\frac{BC}{AB}=sin60^{{\circ}}$

Substituting the given values, we get

$\frac{9}{AB}=sin60^{{\circ}}$

$\frac{9}{sin60^{\circ}}=AB$

$AB=\frac{9{\times}2}{\sqrt{3}}$

$AB=\frac{18}{\sqrt{3}}$

$AB=10.4 feet$

Thus, The length of the support AB is 9 divided by sin 60 degrees.

Svet_ta [14]

Answer:

x = 2y

x - 8 = y + 6

replace x by 2y in the second equation

2y - 8 = y + 6

y - 8 = 6

y = 14

x = 2*14 = 28

Kendra had $28 and Kareem had $14.

12. Use a trigonometric ratio to find the measure of O in the triangle below. Give your answer to the nearest degree.

larisa [96]

Given :-

A right angled triangle with two sides 10cm and 9cm .

To Find :-

The value of theta .

Solution :-

At angle theta , 9cm side will be considered as the perpendicular and 10cm side will be hypotenuse . So , as we know that ;

$\longrightarrow sin\theta =\dfrac{perpendicular}{hypotenuse}$

Substituting the respective values,

$\longrightarrow sin\theta =\dfrac{9cm}{10cm}$

Simplify,

$\longrightarrow sin\theta= 0.9$

Take arcsin both sides ,

$\longrightarrow \theta =sin^{-1}(0.9)$

$\\\longrightarrow\underline{\underline{\theta = 64.15^o }}$

Hence the required answer is 64.15° .
