A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
The tangent line is perpendicular to the radius from the center of the circle to the point of tangency.
ΔDCE is similar to ΔDBA
DC/DB=DE/DA
15/50=DE/40
DE=12
Answer:
27/100
Step-by-step explanation:
27%= 0.27= 27/100 which cannot be reduced
The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
ZCAB angle is congruent to ZBAD
