Hi! :)
So a right triangle is a triangle that contains a ninety degree angle, it's not classified by side length. A scalene triangle is a triangle in which all three sides are different lengths. An isosceles triangle has two sides that are the same length. Either a scalene or an isosceles triangle could contain a right angle, so your answer is yes.
Hope this helps!
In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.
Let the other side is of length b inches .
Now we use pythagorean identity, which is
![a^2 + b ^2 = c^2](https://tex.z-dn.net/?f=%20a%5E2%20%2B%20b%20%5E2%20%3D%20c%5E2%20)
Here, a = 12 and c=18
Substituting these values, we will get
![12^2 + b^2 = 18^2 \\ 144 + b ^2 = 324 \\ b^2 = 324-144 \\ b^2 = 180 \\ b= \sqrt{180} \\ b = 13.4164 inches](https://tex.z-dn.net/?f=%2012%5E2%20%2B%20b%5E2%20%3D%2018%5E2%20%5C%5C%20144%20%2B%20b%20%5E2%20%3D%20324%20%5C%5C%20b%5E2%20%3D%20324-144%20%5C%5C%20b%5E2%20%3D%20180%20%5C%5C%20b%3D%20%5Csqrt%7B180%7D%20%5C%5C%20b%20%3D%2013.4164%20inches%20)
And the formula of perimeter is
![Perimeter = 2(Sum\ of \ legs)](https://tex.z-dn.net/?f=%20Perimeter%20%3D%202%28Sum%5C%20of%20%5C%20legs%29%20%20)
Substituting the values of the two legs, we will get
![Perimeter = 2(12+13.4164) = 50.83 inches](https://tex.z-dn.net/?f=%20Perimeter%20%3D%202%2812%2B13.4164%29%20%3D%2050.83%20inches%20)
Answer:
child's ticket = 4.75 adult ticket=10.75.
Step-by-step explanation:
The cost of an adult ticket is 6 more than that of a child ticket, so will be denoted by c+6. Now, we are told that the cost of four child tickets and two adult tickets is 40.50, so we can put this in an equation and solve for c:
(c+6)+(c+6)+c+c+c+c=40.50
6c+12=40.50
6c=28.50
c=4.75
Therefore the cost of a child's ticket (c) is 4.75 and the cost of an adult ticket (c+6) is 10.75.
