AC=4, AE=7, AD=10, what is the length of AB? A: 1 3/7 B: 2 1/2 C: 5 5/7 D: 17 1/2

11Alexandr11 [23.1K]

Answer:

C. $AB = 5\frac{5}{7}$

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, $\frac{AE}{AC} = \frac{AD}{AB}$

$\frac{7}{4} = \frac{10}{AB}$

Cross multiply

$7*AB = 10*4$

$7*AB = 40$

Divide both sides by 7 to find AB

$\frac{7*AB}{7} = \frac{40}{7}$

$AB = \frac{40}{7}$

$AB = 5\frac{5}{7}$

Need help on this question

Sedaia [141]

Answer:

Step-by-step explanation:

Hey There!

So these triangles are congruent so segment CD is equal to segment DB

so to find x we use the equation

7x+10=10x+7

now we solve for x

step 1 subtract each side by 7

10-7=3

7-7 cancels out

now we have 7x+3=10x

step 2 subtract each side by 7 x

10x-7x=3x

7x-7x= cancels out

now we have

3x=3

step 3 divide each side by 3

3/3=1

3/3 cancels out

now we have

x=1
