All straight lines equal 180 degrees that problem equals 210.
Answer:
Let(-4,6)and (3,-7) be named as A and B
A(-4,6) (x1,y1)
B(3,-7) (x2,y2)
distance between AB= square root(x2-x1)^2+(y2-y1)^2
AB= square root(3-(-4)^2+(-7)-6)^2
AB= square root(3+4)^2+(-13)^2
AB= square root(7)^2+169
AB= square root(49+169)
AB= square root218
AB=14.76 Answer!!!
Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x
![\frac{2x}{2} = \frac{10.72}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B2%7D%20%3D%20%5Cfrac%7B10.72%7D%7B2%7D%20)
![x = \frac{10.72}{2}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%7B10.72%7D%7B2%7D%20)
![x = 5.36](https://tex.z-dn.net/?f=%20x%20%3D%205.36%20)
BD ≈ 5.36
Answer:
x = 60
Step-by-step explanation:
Combine like terms on the left side of the equation: 2x + x = 3x; -1 + 1 = 0 so the total for the left side is just 3x. Now compare it to the full equation that you have left now, 3x = 180 now do 180/3 = 60
Hope this helps!
