The length of the unknown side is 16 meters

<h3>What is a right triangle?</h3>

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

$20^2 = 12^2 +b^2$

Evaluate the exponents

$400 = 144 +b^2$

Collect like terms

$b^2 = 400 -144$

Evaluate the like terms

$b^2 = 256$

Take the square root of both sides

$b = 16$

Hence, the length of the unknown side is 16 meters

ASAP Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 24 f

Nitella [24]

Answer:

D. 6 feet.

Step-by-step explanation:

The third longest side of ABCD is 12 feet long and the third longest side of EFGH is 18 feet long.

As they are similar the corresponding sides are in the same ratio so

12/18 = x/9 where x is the 4th side of ABCD.

2/3 = x/9

3x = 18

x = 6 feet.

The price of an item has increased 15% since last year. However, a person can buy the item for a 25% employee discount. The empl

ANEK [815]

Answer: $200

Explanation:

The employee pays $172.50 and he got 25% employee discount.

If the cost is $100, he pays $(100 - 25) = $75.

So, employee pays =

100

⋅

172.50

= $230.00.

Again, price was increased by 15% last year. So whose cost is $100

is sold by $(100+15) = $115.

When sell price is $115, then cost price is $100. Then,

when sell price is $230, then cost price is

100

115

⋅

230

= $200.

he coordinate grid shows the graph of four equations: A coordinate grid is shown from negative 12 to positive 12 on the x axis a

denis23 [38]

The set of equation that is known to have 5 and 0 as solutions is A and B.

<h3>How to solve for the system of equations.</h3>

From the graph that we have here in this question, we are supposed to identify the equations that have this point.

We can do this by tracing the lines in order to locate 5 and 0 on the grid.

When we trace the bine that has 5 and 0, We would find out that it is traceable to A and B.
