The full circle has  arc 360 degrees 
so length of arc of 140 degrees will be , by proportion,  (60 pi * 140 ) / 360

7. Find the length of AB<br> please answer will mark brainelist :)
Julli [10]

Answer:

A) 17 m  B) 20.8 m

Step-by-step explanation:

I cannot mark on the image but you can find the length of A to the bottom of the shape by subtracting 26-11

26-11 = 15

I will label the triangle as ABC (AB the length we trying to find, BC is 15 *it is angle B to the intercept of A and the bottom of the shape, AC is 8 because it is parallel to the given length 8)

AB is the hypotenuse

We can use the pythagorean theorem  to find length AB (a^2 + b^2 = c^2)

a and b is the legs which is 8 and 15

8^2 + 15^2 = AB^2

64 + 225 = AB^2

289 = AB^2

√289 = AB (to undo a square, you use square roots)

√289 = 17

AB = 17 m

Now we need to find the hypotenuse of AC

the same thing, we did for problem A, use the pythagorean theorem

17^2 + 12^2 = AC^2

289 + 144 = AC^2

433 = AC^2

√433 = AC

√433 is <em>about </em>20.808...

round to the tenth as stated in the directions

AC = 20.8 m

Alaska has a land area of about 1700000 square miles Florida has a land area one tenth of the size of Alaska what is the land ar
AnnyKZ [126]

Answer:

The land area of Florida is 170,000\ mi^2

Step-by-step explanation:

Let

x -----> the land area of Alaska in square miles

y -----> the land area of Florida in square miles

we know that

The linear equation that represent this problem is equal to

y=\frac{1}{10}x ----> equation A

x=1,700,000 ----> equation B

substitute equation B in equation A and solve for y

y=\frac{1}{10}(1,700,000)=170,000\ mi^2

Remember that

Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
