Answer:
Scale Factor states that the ratio that you get when you divide corresponding side lengths of similar figures.
Given: Triangle ABC is congruent to Triangle DEF.
Similar figures have corresponding angles that are equal and corresponding sides that are equal.
To find the scale factor,
you need to find the ratio between the corresponding sides of the triangle.
now, you can multiply each side of one triangle by the same number to get the sides of the other triangle.
∴ The number is the scale factor, that is what we are trying to find.
Answer:
210
Step-by-step explanation:
the % is there to try to throw you off. all you have to do is subtract 285 by 75
which is 210
i believe thats all you do. hope this helps!
Answer: x = 10
Explanation:
Line A is parallel to line B only when the corresponding angles 4x and 3x+10 are congruent
4x = 3x+10
4x-3x = 10
x = 10
To solve, simply layout an equation.
(2x+3)(x+4)=1
Step 1: Simplify both sides of the equation.
2x2+11x+12=1
Step 2: Subtract 1 from both sides.
2x2+11x+12−1=1−1
2x2+11x+11=0
Step 3: Use quadratic formula with a=2, b=11, c=11.
x=-b±√b^2-4ac/2a
So, the answer for this problem is:
x=-11/4+1/4√33 or -11/4+-1/4√33
