Answer:

Venus

Step-by-step explanation:

To find out which star is higher we first want to look at the slopes. So Venus's slope is 10 and Sirius's slope is 9. So by this only we can determine that Venus is higher in the sky.

Use a trigonometric function to find each value of x. Round to the nearest tenth if necessary.

Ulleksa [173]

Answer:

4.0

Step-by-step explanation:

Using trig identity Tangent, tangent is equal to opposite / adjacent side. Therefore tan30 = x/7, because x is the side opposite to 30 degrees and it is adjacent to 7, (note: adjacent side is never the hypotenuse)

To save time, tan 30 = sqrt(3)/3,

sqrt(3)/3 = x/7

x = 7*sqrt(3)/3 ~ 4.041

A TV screen has a diagonal length of 156cm, the angle in the top corner is 37◦. Calculate the height of the TV screen

Arte-miy333 [17]

The TV screen is an illustration of a right triangle

The height of the TV screen is 124.6 cm

<h3>How to calculate the height</h3>

The diagonal is given as:

d = 156 cm

The angle at the top is given as:

Angle = 37 degrees

The height is then calculated using the following cosine ratio

$\cos(37) = \frac h{156}$

Make h the subject

$h = 156 * \cos(37)$

Evaluate

h = 124.6

Hence, the height of the TV screen is 124.6 cm
