Given that triangle ABC has been dilated to form triangle A'B'C' and the vertices of ABC are A(5,3), B(3,7), C(1,4) and vertices of A'B'C' isA'(7.5, 4.5), B'(4.5, 10.5), C'(1.5,6)
then the scale factor for dilation will be as follows:
Taking corresponding vertices SAY A (5,3) and A'(7.5, 4.5)
the scale factor will be:
7.5/5=4.5/3=1.5
Answer: 1.5
Answer:
Step-by-step explanation:
Do u see any similarities between the numbers? Both 12 and -4 have a variable(N). 8 and -7 dont have a variable, so u have to calculate them individually.
One thing to remember is just because there is a minus sign(-) or a plus sign(+) does not mean its addition or subtraction. its the value of the number. the sign to the left of the number is its value. so left of 12 is plus(+), so its a positive. left of 4 is a minus sign(-) so its a negative 4. lastly, left of 7 is minus sign(-), which means its negative 7. now u add.
lets add the variables first:
12n + (-4n) = 8n
add the regular numbers:
8 + (-7) = 1
so its 8n + 1
Answer:
See below
Step-by-step explanation:
11 = 12 = 15 = 16 = 51 each vertical angles are congruent
10 + 11 = STRAIGHT LINE = 180 so 10 = 129 degrees
10 = 13=14 = 17 = 129 degrees each vertical angles are congruent
