Answer:

Part 1) y=6\ units

Part 2) x=3\ units

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABE

we have that

AE=BE

so

Is a 45°-90°-45° triangle

cos(45\°)=\frac{\sqrt{2}}{2}

cos(45\°)=\frac{3\sqrt{2}}{y}

so

\frac{\sqrt{2}}{2}=\frac{3\sqrt{2}}{y}

y=6\ units

In the right triangle EBC

we have that

Is a 45°-90°-45° triangle

sin(45\°)=\frac{\sqrt{2}}{2}

sin(45\°)=\frac{x}{3\sqrt{2}}

\frac{x}{3\sqrt{2}}=\frac{\sqrt{2}}{2}

x=3\ units

What's 4.88 rounded to the nearest tenth......
Ugo [173]
The first decimal point is tenth. 4.88
when rounding, we just look at the number right after the number you want to round to. it's 8 right? since 8 is closer to 10 than 0,
we round it to 4.9
                  (4.8 + 0.10)
