I believe the answer is 20 sorry
Answer:
. It means AC is perpendicular to AB.
Step-by-step explanation:
Vertices of given triangle are A(−2, −2), B(5, −2), and C(−2,22).
Distance formula:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Using distance formula we get
![AB=\sqrt{(5-(-2))^2+(-2-(-2))^2}=\sqrt{7^2}=7](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%285-%28-2%29%29%5E2%2B%28-2-%28-2%29%29%5E2%7D%3D%5Csqrt%7B7%5E2%7D%3D7)
![BC=\sqrt{(-2-5)^2+(22-(-2))^2}=\sqrt{7^2+24^2}=\sqrt{625}=25](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%28-2-5%29%5E2%2B%2822-%28-2%29%29%5E2%7D%3D%5Csqrt%7B7%5E2%2B24%5E2%7D%3D%5Csqrt%7B625%7D%3D25)
![AC=\sqrt{(-2-(-2))^2+(22-(-2))^2}=\sqrt{24^2}=24](https://tex.z-dn.net/?f=AC%3D%5Csqrt%7B%28-2-%28-2%29%29%5E2%2B%2822-%28-2%29%29%5E2%7D%3D%5Csqrt%7B24%5E2%7D%3D24)
According to Pythagoras theorem
![hypotenuse^2=perpendicular^2+base^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3Dperpendicular%5E2%2Bbase%5E2)
![(BC)^2=(AC)^2+(AB)^2](https://tex.z-dn.net/?f=%28BC%29%5E2%3D%28AC%29%5E2%2B%28AB%29%5E2)
Perpendicular = AC
Base = AB
It means AC is perpendicular to AB.
Hence proved.
Answer:Each tennis ball cost 0.67 cents.
Step-by-step explanation:
$10.05 divided by 15 equals 0.67 cents.
0.67 x 15 = $10.05
Answer:
No, Pythagorean Theorem can't be used here for finding the missing sides of the triangle.
Because Pythagorean Theorem is used in triangles having one of its sides right angled but here in the diagram non of the sides of the triangle are right angled .
Answer:
45 times 4/9 times three-fifths
Step-by-step explanation:
4/9 of the 45 questions are done at a rate of 3/5 of a minute. If he finished 5/9 of the 45 then he has 4/9 of the 45 left and the 3/5 of a minute would be continued in the 4/9 of the 45.
