Answer:
Two geometric figures are similar if their corresponding angles are equal and their corresponding sides are proportional. A ratio is a fraction which compares two quantities. In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
Step-by-step explanation:
Answer:
x = 19
Step-by-step explanation:
All triangle angles equal 180
3x + 9 + 2x + 4x = 180
9x + 9 = 180
9x = 171
x = 19
Answer: b and d
Step-by-step explanation:
Since the roots are x=2 and x=6, we can write the equation as
Substituting in the coordinates of the vertex,
So, the equation is
On expanding, we get
X would be 4 so the answer is B
