In right triangle XYZ, triangle Y is the right angle and m angleX = 60 degrees. If YZ= 4 what is XY
Marina86 [1]

Answer:

XY = \frac{4\sqrt 3}{3}

Step-by-step explanation:

<em>The question is illustrated with the attached figure.</em>

Required

Determine XY

To solve for XY, we make use of the tan function, which states that:

tan\theta = \frac{Opposite}{Hypotenuse}

In this case:

tan\ 60= \frac{YZ}{XY}

Substitute 4 for YZ

tan\ 60= \frac{4}{XY}

Make XY the subject

XY= \frac{4}{tan\ 60}

tan\ 60 =\sqrt 3

So, the expression becomes:

XY = \frac{4}{\sqrt 3}

Rationalize:

XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}

XY = \frac{4\sqrt 3}{3}

Please help asap !!!!!

Answer:

<em>XY = 92 units</em>

Step-by-step explanation:

<u>Similar Shapes</u>

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units
