Let
C=Cynthia's age today
A=Abigail's age today
then
at all times
A=C+8......................(1)
twenty years ago,
A-20=3(C-20)
simplifying
A=3C-40...................(2)
Equate (1) and (2),
C+8=3C-40
8+40=3C-C
C=24
=>
A=32
Check: A-C=8... ok A-20=12 C-20=4 => (A-20)=3(C-20) ...ok
Answer:
Abigail is 32, Cynthia is 24.
Answer:
true
Step-by-step explanation:
all the sides match up. One side (the base) is shared which means they are the same length. The triangle at the top has a single hash on a side and so does the bottom one. This means they are the same length. The same thing occurs with the last remaining sides, they are congruent because they both have two hash lines. Since all three sides of both triangle add up, the triangles ARE CONGRUENT.

Answer:
40.60 degrees to the nearest hundredth.
Step-by-step explanation:
Tan A = opposite side / adjacent side = 6/7'
The angle whose tangent is 6/7 is 40.60 degrees.
P(x) = 1 - 2x² +3x +2x⁵
has one variable, x, and has terms of degree 0, 2, 1, and 5. The highest degree is 5, so it is a 5th-degree polynomial in x.
