Answer:
Cosine
Step-by-step explanation:
If the triangle is not right-angled, and there is not a matching pair, you will need the Cosine Rule..
and the formula used will be: 
In the opposite case if the triangle is not right-angled, and there is a matching pair, you will need the Sine Rule..
Im gonna answer this in calculator form. It might be non-calculator but if y = 20.07 when x = 9, than u can divide 9 by 9 to get 1. 1 x 14 = 14. Now vise versa. 20.07 / 9 = 2.23. 2.23 x 14 = 31.22
= 31.22.
Thanks please heart because im depressed. bye
Answer:
(0,-1)
Step-by-step explanation:
Let the ends of the line segments be A(-4,3) and B(5,-6).
Ratio=4:5
By the concept of cordinate geometry,
x=(mx2+nx1)/(m+n)
y=(my2+ny1)/(m+n)
where m and n is the ratio m:n.
So, here the cordinates are
x={4(5)+5(-4)}/(4+5)
x=(20–20)/9
x=0
y={4(-6)+5(3)}/9
y={-24+15}/9
y=(-9)/9
y=(-1)
Therefore the cordinates of the point that divides the given line segment in the ratio 4 : 5 is (0,-1)
:)
x = 3
2x + 7 =....
2 (3) + 7 = 6 + 7 = 13
this is my answer how about my answer ?
