Answer 1

Step-by-step explanation:

You might start by recognizing that ABDABD and ADCADC are similar triangles, because they share the angles ∠DAC∠DAC and 9090 degrees. Therefore,

y4=zx=9y

y4=zx=9y

We can rearrange y/4=9/yy/4=9/y to obtain y2=36y2=36, so y=6y=6, which allows us to answer (b). Then by the Pythagorean theorem,

42+x2=y2=36

42+x2=y2=36

so x2=20x2=20, which means that x=20−−√x=20, which allows us to answer (a). Finally, rearranging the first equation above gives us

z=xy4=620−−√4

z=xy4=6204

which allows us to answer (c)
