Question

Hello!! some help pls :>

Answer 1

Answer: AB = 22 cm BC = 11 cm CD = 11 cm BC + CD = 22 cm

Explanation:

The problem tells us that AC is 33 cm, and we can see that AB and BC make up AC.

The problem tells us that AB measure 2x, and BC measures x, so we now have the equation 2x + x = 33 cm.

We can solve for x.

2x + x = 33

3x = 33

x = 11 cm

Now, we know that AB is 22 cm, and BC is 11 cm.

The problem also tells us that CD is congruent to BC, so we know that CD is 11 cm.

BC + CD = 11 cm + 11 cm = 22 cm

Answer 2

AB = 22

BC = 11

CD = 11

BC + CD = 22

Explanation:

AB + BC = AC

2x + x = 33

• Add variables.

3x = 33

• Divide both sides by 3.

x = 11

• Segment BC and segment CD are equal segments.

So,

BC + CD = 2x

Since we know x = 11, then BC + CD will be = 22
