-0.83 for it’s the lowest number
Assuming this is a system of equations, here is how to find x.
2x + 3y = 45
x + y = 10
Multiply x + y = 10 by 2 so you are able to use the elimination method.
2x + 3y = 45
2x + 2y = 20
Subtract.
y = 25
Now that we've found y, we can plug it in to find x.
x + 25 = 10
Subtract 25 from both sides.
x = -15
1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
Answer:
<6 = 117 degrees, <7 = 63 degrees
Step-by-step explanation:
- <3 and <6 are consecutive interior angles, meaning they are supplementary.
- <3 and <7 are same-side exterior angles meaning they are congruent.
