Answer:
A
Step-by-step explanation:
∆ABC is similar to ∆DEF if and only if the ratio of their corresponding side lengths are the same.
Let's find out:
DE/AB = 10/5 = 2
EF/BC = 8/4 = 2
FD/CA = 12/6 = 2
The ratio of their corresponding side lengths are equal, therefore, ∆ABC is similar to ∆DEF based on the SSS Similarity Theorem.
Answer:
12
Step-by-step explanation:
Answer:
x=92
Step-by-step explanation:
those to angles are supplementary meaning that they add up to equal 180
so you set up the equation 180=x+x-4
180=2x-4
step 1 add 4 to each side
184=2x
step 2 divide each side by 2
x=92
so the angles equal 92 and 88
Answer:
n = -33
Step-by-step explanation:
Let n = number
Sum of a number and 9
(n+9)
is tripled
3(n+9)
the result is six less then twice the number
2n-6
3(n+9) = 2n-6
Distribute
3n+27 = 2n-6
Subtract 2n from each side
3n-2n +27 = -6
n +27 = -6
Subtract 27 from each side
n+27-27 = -6-27
n =-33
Answer:
B. x = 2, y = 6
