Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
?=115-50=65°
Answer: (x + [-1], y + [1])
Step-by-step explanation:
<em>See attached. </em>We can draw, or picture it in our heads, what the reflection would look like. Then we can pick one (or multiple to test) points and see the translation.
We can also test with a set of points. B', (2, 4) becomes G in the transformation. G is at (1, 5)
(1 - 2, 5 - 4) -> (-1, 1)
In real-life physics, acceleration due to gravity will change respect to altitude. Check out the attached image (source: Wikipedia).
However, in high-school physics, acceleration due to gravity is represented by the letter g, which has a value of 9.81 meters per second squared.
This means that an object being dropped straight down will be moving 9.81 meters per second faster than it was 1 second ago. I hope this helps! :)
Answer:1=70 2=65 3=95
Step-by-step explanation:
Angles in a triangle add up to 180°
180-45=135-65=70
1=70°
Angles on a straight line add up to 180°
180-45=135-70=65
2=65°
Angles in a triangle add up to 180°
180-65=115-20=95
3=95°
