FIND THE LENGTH OF AC ​

Answers

Answer:

AC=18

Step-by-step explanation:

To find AC, use the Pythagorean Theorem.  Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b².  12²-8²=b²

144-64=b²

80=b²

√80=√b²

8.94427191=b

That is for one of the two right triangles that make up the tent.  Since there are 2 triangles, 8.94427191 only equals BC or AB.  So, multiply 8.94427191×2=17.88854382 to find the length of AC.

AC= 18

Answer:

x=3

y=1

Step-by-step explanation:

-2x - 7y = -13

3x + 6y = 15

3(-2x - 7y = -13) = -6x - 21y = -39

2(3x + 6y = 15) = 6x + 12y = 30

-6x - 21y = -39

----------------------  The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9

6x + 12y = 30

Therefore, you can say that -9y = -9 so y = 1

FInally, plug that back into either one of the original equations:

3x + 6(1) =15
