Answer: The first and fourth pair of polygons are similar.


Step-by-step explanation:

If two polygons are similar then their corresponding sides are proportional.

Let's check

  • In the first pair there are two rectangles and their dimensions are proportional as

\frac{22}{13.75}=\frac{16}{10}=1.6

  • In the second pair there are right triangles but their dimensions are not proportional as

\frac{18}{8}=2.25 and \frac{30}{17}=1.76

  • In the third pair there is one isosceles triangle and other is equilateral triangle, which can not be similar as they have different type of triangles.
  • In the fourth pair there are two right trapezoid and their dimensions are proportional as

\frac{7.5}{3}=\frac{30}{12}=\frac{12.5}{5}=\frac{20}{8}=2.5

Determine if the triangle with the given sides is acute, obtuse, or right. 36, 49, 60
kotykmax [81]
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
</span>1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.

if sum > 3rd side²   Acute Triangle
if sum = 3rd side²   Right Triangle<span>
if sum < 3rd side²   Obtuse Triangle

1) 1,296   2,401   3,600
2) Sum = 3,697
3) </span><span>3,697 is greater than 3,600
Therefore, the triangle is acute.

Alex purchased a new car for $28000. The car depreciates 7.25% each year. what will the price be in 5 years?
dalvyx [7]
Use the depreciation formula.

\sf p(1-r)^n

Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:

\sf 28000(1-0.0725)^5

Simplify by subtracting:

\sf 28000(0.9275)^5

Simplify the exponent:

\sf 28000(0.6864)

Multiply:

\sf\approx\boxed{\sf\$ 19219.20}
