Answer:
option one is right
Step-by-step explanation:
the very first triangle is the 30 -69 -90 degree triangle ️
Hiya!
First, translate vertex A to vertex X. Next, rotate angle ABC to align the sides and angles.
How I got this? Simple! Notice how both shapes are the exact same, down to the exact measurements. Now, imagine a four-quadrant grid with (0, 0) is between point C and Y. ABC is in the top left quadrant and XYZ is in the lower right. If you rotated the whole thing, they'd overlap. Vertex A is actually vertex X, theoretically.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
Answer:
∠3=80°
Step-by-step explanation:
∠5=∠2 (alternate angle)
∠5=38
so ∠2=38
∠6=62
∠3+∠6+∠2=180
∠3+62+38=180
∠3=180-100=80
Step-by-step explanation:
162 kilometers = 162000 meters
1 hour = 3600 seconds.
162,000 meters/3600 seconds=45 meters/second=45 m/s
45*10=450
I think it is y=mx+b
y=2x+5; y=8x+-3. correct me if lm wrong
