Answer 1

3. Look at the picture.

Use Pythagorean theorem:


`x^2=3.6^2+5.5^2\\\\x^2=12.96+30.25\\\\x^2=43.21\to x=√(43.21)\\\\\boxed{x\approx6.6}`


4.
Use Pythagorean theorem:


`3^2+\left((x)/(2)\right)^2=6.5^2\\\\9+(x^2)/(4)=42.25\ \ \ |-9\\\\(x^2)/(4)=33.25\ \ \ \ |\cdot4\\\\x^2=133\to x=√(133)\\\\\boxed{x\approx11.5}`


5.

`\widehat{AB}\ \cong\ \widehat{DE}`
