Do you see the right triangle in the picture ?

The TANGENT of angle-x is 10m/17.3m. Do the division, find that number, then use your calculator or search online to find the angle that has that number for its tangent.

I get roughly 30 degrees, but you should check me.

We know that :

$Tan\theta = \frac{Opposite\;Side}{Adjacent\;Side}$

From the Figure :

$Tanx = \frac{Height\;of\;the\;Tree}{Shadow\;of\;the\;Tree}$

Given : Height of the Tree = 10 m

Length of its Shadow = 17.3 m

⇒ $Tanx = \frac{10}{17.3} = 0.578$

⇒ $x = Tan^-^1(0.578)$

⇒ x° = 30°

Answer:

0.44

Step-by-step explanation:

See the picture below.

Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.

Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.

For angle J, leg LK is the opposite leg.

The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.

$\sin J = \dfrac{opposite~leg}{hypotenuse}$

$\sin J = \dfrac{39}{89}$

$\sin J = 0.43820...$

Answer: option d. C (0,3), D (0,5).

Justification:

1) The x - coordinates of the vertices A and B are shown in the diagrama, They are both - 4, so the new vertices C and D must be in a line parallel to y = - 4.

2) The y-coordinates of the vertices A and B are also shown in the diagrama. They are equal to 3 and 5 respectively.

3) We can see that the new points C and D must be over a parallel line to y = - 4 and that their distance to the points A and B has to be the same distance of the point R and S to U and T.

That distance is 4, so the line may be y = - 7 or y = 0.

4) If the line is y = 7 the points C and D would have coordinates (-7,3) and (-7,5), but this points are not among the options.

5) If the line is y = 0 the points C and D would have coordinates (0, 3) and (0,5), which is precisely the points of the option d. That is the answer.

PLEASE HELP ME, ILL BRAINLIEST YOU ill give u 30 points if you help

Answer:

$x = 58$

$y = 90$

Step-by-step explanation:

This is a rhombus becuase it a quadralterial and it has four right triangles, and it diagonals bisect each others so it cant be a trapezoid, and paralleolgram. and it doesnt have four right corner angles so it cant be a square or rectangle or kite.

A rhombus inner angle measure is 90 degrees.

$y = 90$

This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.

Since a rhombus bisects angles, angle x measure 58.
