Answer:

yes Z= 35

Step-by-step explanation:

3  = 15

7   =  z

Cross multiply:

3 * z = 7 * 15

Simplifying

3 * z = 7 * 15

Multiply 7 * 15

3z = 105

Solving

3z = 105

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Divide each side by '3'.

z = 35

Simplifying

z = 35

3/7 = 15/z

using cross products

3z = 7*15

3z = 105

What is BC?<br><br> Enter your answer in the box<br><br> _units
laiz [17]

Answer:

<h2>BC = 25</h2>

Step-by-step explanation:

It's an isosceles triangle (congruent angles ∠C ≅ ∠B).

Therefore AC = AB.

We have the equation:

4x+1=2x+23        <em>subtract 1 from both sides</em>

4x=2x+22       <em>subtract 2x from both sides</em>

2x=22          <em>divide both sides by 2</em>

x=11

Substitute the value of <em>x</em> to the expression BC = 3x - 8:

BC = 3(11) - 8=33-8=25
