What is the value of x in the triangle?

D

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exacy value

tan30° = = , then

tan30° = = = ( cross- multiply )

3x = 15 ( divide both sides by 3 )

x = 5 → D

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

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car
