The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
Answer:
k=6
Step-by-step explanation:
Line partition formula
1/b(x2-x1)+x1, 1/b(y2-y1)+y1
Where b is the number partitions.
We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.
1/b(17-2)+2=7
1/b(15)=5
1/b=1/3
b=3
so the partition is 1/3

So let find the y coordinate

So our y coordinate is 6.
It is 9 because you have a 30,60,90 triangle, and then you can use pythagorean theorem.
The length is 10

hope this helps :)
77/5=99/x
77x=5*99
77x=495
x=495/77
x=6.4
