Triangle ABC is shown below.
Andrew [12]

Answer:

C.) 14

Step-by-step explanation:

Look at the triangle: angles b and c have the same arch, so they are congruent.

In a triangle, if two angles are congruent, then the triangle is isosceles, having two equal sides.

The sides opposite the congruent angles are congruent:

∠B → opposite side → AC

∠C → opposite side → AB

The sides AB and AC are equal. Make an equation:

AB=AC\\\\2x=3x-7

Simplify the equation, solving for x. Add 7 to both sides:

2x+7=3x-7+7\\\\2x+7=3x

Subtract 2x from both sides:

2x-2x+7=3x-2x\\\\7=x

The value of x is 7. Insert the value of x into the given length of AC:

AC=3(7)-7

Simplify multiplication:

AC=21-7

Subtract:

AC=14

Therefore, the length of the line segment AC is 14.

In six years, clem kadiddlehopper will be five time as old he was 26 years ago. how old is he now?
levacccp [35]

Answer:

he is currently 34

Step-by-step explanation:

x + 6 = 5(x-26)

x + 6 = 5x - 130

 +130        +130

x + 136 = 5x

-x             -x

136 = 4x

/4       /4

x = 34

You can check your work as well:

34 + 6 = 40

34 - 26 = 8

8 x 5 = 40
