Answer:

The length of <u>DB is 26.</u>

Step-by-step explanation:

In figure-1 ,we can see AB is tangent of length 24 and XD is radius of circle of length 5

Since AD  is diameter so, it will be calculated as 2*radius = 2* 5 =10

Tangent at any point of circle is perpendicular

so, right triangle ABD at ∠A

In ΔABD

By Pythagoras

hypoteneous² = base² + prependicular²

               BD²  = AD² +  AB²

               BD²  = 10² +  24²

               BD²  = 100 +  576

               BD²  = 676

   Taking root booth the sides in above expression,

             √( BD)²  = √676

               BD = 26

Hence, the length of <u>DB is 26.</u>

So since xd is 5 that means ad is 10
now you have 2 sides all you need is to find the last side you can use Pythagorean theorem and get 26 for db
answer 26.

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
Fantom [35]

Answer:

108 ft²

Step-by-step explanation:

For the polygon on the left, we are given the length of one side (3 ft) and the total area (27 ft²). With this information, we can determine the length of the other side - 9 ft. I found this by dividing 27 ft² by 3 ft, giving me the final result of 9 ft.

Next, we have to find the other side of the polygon on the <em>right</em> so we can ultimately determine its area. It looks like there is a scale factor of 2 between the two polygons, since 3 × 2 = 6. We know that the bottom side of the left polygon is 9, so multiplying 9 by 2 should give us the bottom side of the polygon on the right. 9 × 2 = 18.

Now, we have the side lengths for the polygon on the right and can determine its area. What is 6 ft × 18 ft? Well, the answer is 107 ft², and this is the answer to the question.

Hopefully that's helpful! :)

How much times can 6 go into 48
DENIUS [597]
6 can go into 48 8 times. How I figured out?
Start multiplying from a small number like
6×6= 36
6×7=42
6×8= 48
until you see your number 48, or a number that is lower that 48, but can not go any higher than 48.

Which graph represents the solution set of y=x^2+4x+3and y=2x+6?
rewona [7]

Answer:

(1,8) and (-3,0)

Step-by-step explanation:

We simply graph the two functions in the same graph. The solution set to the system is given by the points where the two functions intersect. For this case, the two functions intersect at;

(1,8) and (-3,0)

The solution set is thus; (1,8) and (-3,0)
