What is bc ? enter your answer in the box. units

25

Step-by-step explanation:

I'll explain in detail for those of you that want to know.

You know that since angles B and C are congruent to each other that this triangle is an isosceles triangle. Therefore, sides AB and AC are congruent to each other because that is a property of an isosceles triangle.  

To solve for x, place the expressions of sides AB and AC equal to each other and solve for the unknown variable.

4x + 1 = 2x + 23

You should get that x = 11.  

Substitute x = 11 into the expression for side BC to solve for the length of that side.  

f(11) = 3(11) - 8  

f(11) = 25  

Thus, length of side BC is 25 units.

Use this way of solving for all your future questions. It's really simple :)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
