Answer: AB≅EF, ∠B≅∠E, BC≅DE
Step-by-step explanation:
AB and EF are both marked with one line, making them congruent.
The same goes for BC and DE since they are marked with two lines.
Angles B and E are congruent because of the marking that is specified in both figures.
B. Acute and isosceles
Since the angle is less than 90 degrees and it has two equal sides
-2x + 3a - 6 - 5x - 7a....combine like terms
-7x - 4a - 6 <==
Answer: constant of proportionality - the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
166 is the total of how many jumps they made all together
