1) $\overline{AB} \perp \overline{BD}$ , $\overline{AB} \cong \overline{DB}$ , $\overline{AC} \cong \overline{DE}$ (given)

2) $\angle ABD$ is a right angle (perpendicular lines form right angles)

3) $\triangle ABD$ and $\triangle DEB$ are right triangles (a triangle with a right angle is a right angle)

4) $\triangle ABD \cong \triangle DEB$ (HL)

5) $\angle ACB \cong \angle DEB$ (CPCTC)

Which of the following shows a group of possible angles a triangle could have?

maw [93]

Answer:

D) 50, 60, 70

Step-by-step explanation:

The reason why it's D since a regular triangle equals up to 180 degrees in total and D is the only one that equals 180.

50+60+70= 180 degrees

Answer: C. 150 km²

Step-by-step explanation:

Use similar triangle proportion to find x:

$\dfrac{x}{4.5}=\dfrac{15.3+7.4}{7.4}\\\\\\x=\dfrac{4.5(22.7)}{7.4}\\\\\\x=13.8\\\\\text{Notice that x is the diameter of the circle}\implies r=\dfrac{13.8}{2}=6.9\\\\\\\text{Find the area of the circle using }A=\pi r^2\\A=\pi (6.9)^2\\\\.\ =\pi (47.6)\\\\.\ =149.6\\\\.\ \approx150$
