What is the value of X for the picture

Given:

One secant is x+ 5 and 8

Other secant is x + 1 and 9

To find:

The value of x

Solution:

If two secant segments intersect outside a circle, then the product of one segment and its external segment is equal to the product of other segment and its external segment.

External segment = 8 + x + 5 = x + 13

Another external segment = 9 + x + 1 = x + 10

Subtract 90 from both sides.

Subtract 8x from both sides.

The value of x is 14.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
