Correct choices are A, C and D

Step-by-step explanation:

Consider two right triangles:

first with legs h=529 m and 229 m;second with legs h=529 m and 347 m.

Then

$\tan x=\dfrac{529}{229},\\ \\\tan y= \dfrac{529}{347}.$

Since

$\dfrac{529}{229} \dfrac{529}{347},$

then $\tan x\tan y\Rightarrow xy$ (option A is true).

You are given two parallel lines. Angles x and v and y and w are alternate interior angles, then x=v, y=w. This means that option B is false and option C is true. Option D is also true, because

$xy \text{ and } x=v \text{ gives that } vy$

and option E is false, because

$xy \text{ and } y=w \text{ gives that } xw.$

Answer from: romet31

The true statements from the size of the angles of the given triangle are $xy, \ v= x, \ \ w = y, \ \ y w$ .

The given parameters;

Height of the balloon, h = 529 mLength of first half of AB = 229 mLength of second half AB = 347 m

The length of A to the balloon point is calculated as follows;

$AT^2= 529^2 + 229^2\\\\AT = \sqrt{529^2 + 229^2} \\\\AT = 576.4 \ m$

The length of B to the balloon point is calculated as follows;

$BT^2 = 347^2 + 529^2\\\\BT = \sqrt{347^2 + 529^2} \\\\BT = 632.7 \ m$

The size of the interior angles of the triangle depends on the size of the length opposite the angle.

The largest angle is x opposite to 632.7 mThe second largest angle is y opposite to 576.4 m

For exterior angles;

v = x (alternate anglesw = y (alternate angles)

Thus, we can conclude that the true statements from the size of the angles of the given triangle are $xy, \ v= x, \ \ w = y, \ \ y w$ .

Answer from: Quest

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

Answer from: Quest

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 $\sqrt{x}$ and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 $\sqrt{x}$ is shifted from its position in all the four options.
