It is 6 because 1000 would not be the appropiate answer
Answer:
D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin
Step-by-step explanation:
Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a <em>90°-clockwise rotation </em>option, we have to go with something similar to that, which would be a <em>270°-counterclockwise</em> <em>rotation</em><em>.</em><em> </em>If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

Answer: Isosceles
<u>Step-by-step explanation:</u>
Given: AB || DE , BC is a transversal
∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°
∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°
By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°
Triangle is isosceles because ∠A ≅ ∠C
