AC = 16, AB = x + 1, and BC = x + 7. What is the measure of the length of AB? HELP

saveliy_v [14]

Answer:

Step-by-step explanation:

AC=AB+BC

so 16=x+1+x+7

which simplifies to 16=2x+8

subtract eight from both sides to get 8=2x

then divide by 2 to get that x=4

AB=x+1, which substitutes into 4+1=5

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

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

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

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

There exist two complex numbers $c$, say $c_1$ and $c_2$, so that $3 + 2i$, $6 + i$, and $c$ form the vertices of an equilateral

leva [86]

Answer:

The answer is " $\sqrt{12.5}$ "

Step-by-step explanation:

$\to (3,2), \ (6,1)$

Distance $=\sqrt{9+1}=\sqrt{10}$

midpoint height $=\sqrt{10+2.5}=\sqrt{12.5}$

let

Gradient $= \frac{1}{-3}$

Perpendicular Gradient $= 3$

midpoints $= (4.5, 1.5)$

Similar to perpendicular

Now I'll obtain the perpendicular bisector solution

An equation of the center circle $(4.5,1.5)$ radius will be $\sqrt{12.5}$ .

Step-by-step explanation:

l x 3 = c

k + 5 = l

(c + l + k) x 2 = 25

c = 33

l = 11
