In the right ABC above, the length of the side BC is 4.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Given;
Side BA= [tex]\sqrt{11}[/tex]
Side AC= [tex]\sqrt{5}[/tex]
BC^2=BA^2+AC^2
BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2
BC^2= 11+5
BC^2= 16
BC= 4
Therefore, the Pythagoras theorem gives answer 4

Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that [tex]cos(x)=\frac{28}{39}[/tex]
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side
[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1

QUESTION:
What is mBDG?
Answers
Answer:
242
Step-by-step explanation:
Circles have a total of 360°
mDBG does not include mBA or mGA
This means that mDBG = 360 - ( mBA + mGA )
mBA = 28° ( this is given )
mGA = 90° ( this is also given; it's indicated by the right angle )
Thus, mDBG = 360 - ( 28 + 90 )
28 + 90 = 118
mDBG = 360 - 118
360 - 118 = 242
Hence, mDBG = 242

Write the equation in standard form for the circle with center (-7,0) and radius 4 7
Answers
Answer:
x² + y² - 8x -14y - 105 = 0
Step-by-step explanation:
The centre of the circle is (-7,0) and the radius is (4,7) . Firstly let's find the radius using Distance formula .
=> D = √{ (-7-4)²+(0-7)²}
=> D = √ 11² + 7²
=> D = √ 121 +49
=> D = √170
Now using the standard equation of circle ⭕ ,
=> ( x - h)²+(y-k)² = r²
=> ( x - 4)²+(y-7)²= (√170)²
=> x² + 16 -8x + y² + 49 -14y = 170
=> x² + y² -8x -14y = 170 -65
=> x² + y² - 8x -14y - 105 = 0
• Hence the equation of circle is x² + y² - 8x -14y - 105 = 0 .Start at the school. Go 6 units left and 4 units down to arrive at the library. Enter the coordinates of the library.

On a ship the ratio of crew members to passengers is 1:15. There are 540 passengers. How many crew members are there?
Answers
Answer: 36
Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540
Answer:
36 Crew members
Step-by-step explanation:
Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.
Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.
Double checking your answer:1/15=0.06666666667...
36/540=0.06666666667...

A dirt bike has been marked down 12% and now costs $4286.70. What was the original cost?
Answers
Answer:
$4871.25
Step-by-step explanation:
You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:
0.88x = 4286.70
You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:
x = 4871.25

Will mark it the brainliest plsss fast!
Answers
Answer:
option 1.
circle
Step-by-step explanation:
A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.
What determines the shape of the section now, is the angle at which the cone was sliced.
Normally, the base of a cone is a circle. If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.
If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.
