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]

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
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
if sum < 3rd side² Obtuse Triangle

1) 1,296 2,401 3,600
2) Sum = 3,697
3) 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:

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