Answer:
(2.5,10.5)
Step-by-step explanation:
In the abscissa (x), A is in the middle point between 0 and 5:
In the ordinate (y), A is in the middle point between 9 and 12:
Then, the coordinates of point A are:
A=(x,y)→A=(2.5,10.5)
Answer:
d=13.8
Step-by-step explanation:
secant-secant theorem: (a+b)b=(c+d)d
(14+20)14=(16+d)16
34*14=256+16d
476=256+16d
220=16d
d=13.75
Answer:
x=25
Step-by-step explanation:
The area of a traingle is 180 degrees, so we subtract 30 and 50 from 180. we are then left with 100 degrees, divide by 4 and we get that x=25.
Answer cannot be simplified but u would get 7.549
