Answer:
-12.5% error
Step-by-step explanation:
Step 1. Subtract the actual value (40) from the estimated value (35)
35-40 = -5
Step 2. Divide the results (-5) with the actual value (40)
-5/40=-0.125
Step 3. Find the percent by multiplying the result (-0.125) by 100
-0.125 * 100 = -12.5
Therefore, the percent error was -12.5%

Answer:
A, C, D
Step-by-step explanation:
All three triangles can be proved congruent, so corresponding angles are congruent.
∆JKL ≅ ∆MNO ≅ ∆PQR
__
So, the statements that are true are ...
A) rigid motion can map ∆JKL to ∆MNO
C) ∆JKL can be proved congruent to ∆PQR
D) ∠N can be proved congruent to ∠Q
_____
<em>About the other choices</em>
B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.
E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.
