Answer:

a = -3.

Step-by-step explanation:

a - 2 = (3 + 6a) / 3   Simplifying the right side:

a - 2 = 1 + 2a

a - a - 2 = 1 + 2a - a

-2 = 1 + a

a = -3.

Determine if the statement is true or false<br> The figures below are similar
artcher [175]

Answer:

True

Step-by-step explanation:

The polygons given have 5 sides, so the sum of their interior angles is (5-2) * 180 = 540. Next, there are 4 pairs of corresponding sides. Writing those sides as a, b, c, and d, for each pentagon, we can write

540 = a + b + c + d + missing angle

540 = a + b + c + d + missing angle

As is shown here, if a, b, c, and d are the same, 540 - (a+b+c+d) = missing angle is the same as well. Therefore, there are 5 corresponding angle pairs for the two polygons. Furthermore, because there are only 5 angles for each polygon, and because having all corresponding angles be equal makes polygons similar to each other, the polygons given are similar
