Answer:
<u>Option B. Side YZ is the same length as side Y'X'.</u>
Step-by-step explanation:
XYZ is reflected across the y-axis and then translated down 6 units to form X'Y'Z'.
So, X' is the image of point X
Y' is the image of point Y
Z' is the image of point Z
And ΔXYZ ≅ ΔX'YΔ'Z'
And the corresponding length are congruent
We will check the options:
A. X has the same measure as X'. ⇒ True
B. Side YZ is the same length as side Y'X'. ⇒ Wrong
Because YZ will be translated to Y'Z'
C. Z has the same measure as Z'. ⇒ True
D. Side XZ is the same length as side X'Z'. ⇒ True
<u>So, The answer is option B. Side YZ is the same length as side Y'X'.</u>
<u>Answer:</u>
P(3 blue) = 1/5
<u>Steps:</u>
P(3 blue) = 2/3 × 3/5 × 1/2
P(3 blue) = 6/30
P(3 blue) = 1/5
<em>that's 20%</em>
Since you said angle, I assume you mean a triangle, so:
Take the number of the angles you have and add them, then, subtract it by 180. It gives you the missing angle of your triangle!
Answer:
The unknown angle is 80
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
Let the unknown angle be x
20+80+x = 180
Add like terms
100+x = 180
Subtract 100 from each side
100-100+x=180-100
x = 80
