DE // BC
so AD/AB = AE/AC
The Triangle ADE is similar to triangle ABC
Answer is the first option
Triangle A ≡ Triangle A
Answer:
y=-23/6
Step-by-step explanation:
in the equation, you would need to first subtract y and -2y which equals -y=> (this would be on the left side of the equation)
then, subtract -1/2 on both sides of equation and put that in the right side of the equation.
add 1/3 on both sides of equation and put that in the right side of equation as well.
now, you have this equation: -y=4-1/2+1/3
you have to make all the fractions have the same denominator by multiplying which results for 4 to be 24/6, -1/2 to be -3/6, and 1/3 to be 2/6
your resulting equation would be -y=24/6-3/6+2/6
and when you solve the right side of the equation by subtracting and adding, you get 23/6
now, the equation would be -y=23/6
finally, you just have to divide -1 on both sides of the equation and you would get y=-23/6 as your final solution.
I hope that helps :)
Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
