Answer:
x = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
Note that ΔBCD is a 3- 4- 5 triangle ( Pythagorean triple), hence CD = 4
Substitute given values into the equation
=
( cross- multiply )
3x = 24 ( divide both sides by 3 )
x = 8
Answer:
-11
Step-by-step explanation:
Subtract 3 everytime
the first one that is x-99....... goes to the second answer box
the second that is x-51......... goes to the first answer box
the third that is 150+x......... goes to the fourth answer box
the fourth that is 69-x......... goes to the third answer box
