Answer:

AC = 12.5 cm

Step-by-step explanation:

use cosine law c^2 = a^2 + b^2 − 2ab cos(C)

c^2 = 6^2 + 10^2 - 2(6)(10)(cosin100)

c^2 = 156.84

c= √156.84

c= 12.5 cm

The cosine rule is used when we are given either three sides or two sides and the included angle.

Line ab contains the points a(-2,3) and b(4,5). Line ab has a slope that is

gayaneshka [121]

Given two points $A = (A_x, A_y),\ B = (B_x,B_y)$ , the slope of the line passing through the two points is

$m = \dfrac{A_y-B_y}{A_x-B_x}$

So, in your case, you have

$m = \dfrac{3-5}{-2-4} = \dfrac{-2}{-6} = \dfrac{1}{3}$
