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
The answer is 5-3/2x. Hope this helps :)
Answer:
hmmmmmm Okay From what question?
Answer:
10.7
Step-by-step explanation:
Let x be the missing side.
The rectangles are similar. Wich means:
● 8/9 = x/12
Cross multiply
● 9x = 8×12
● 9x = 96
Divide both sides by 9
● 9x/9 = 96/9
● x = 10.666
Round it to the nearest unit
● x = 10.7
