Answer:
Yes
Step-by-step explanation:
A rigid motion is a transformation that preserves the size and shape of the original image. A rigid motion was used to transform image A into image B and then a rigid motion was used to transform image B into image C.
Answer: Measure angle H = 42°
Step-by-step explanation:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"
In given we have,
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H
Based on the above rule,
measure angle E = measure angle D + measure angle H
We are given this:
angle E = 87°
angle D = 45°
Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°

Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
