Triangle ABC is shown below.<br> What is the length of line segment AC?
Rzqust [24]

Answer:

The length of the line segment AC is equal to 14

Step-by-step explanation:

The triangle above is an isosceles triangle, In an Isosceles triangle the two angles; B and C are the same, hence the two sides; AB and AC are also the same.

AB=2x    and AC= 3x - 7

AB = AC

which implies;

2x = 3x - 7

subtract 3x from both-side of the equation

2x - 3x = 3x -3x -7

-x = -7

Multiply through by -1

x = 7

But we were ask to find the the length of the line segment AC

AC = 3x - 7

substituting x = 7 into the above equation will yield;

AC = 3(7) - 7 = 21 - 7 =14

Therefore the length of the line segment AC is equal to 14

Trina ran 2 1/2 miles of Friday, 2 3/4 miles on Saturday and 3 mies on SUnday. The next week she ran the same amount. How far in
vodka [1.7K]

Answer:

16 \frac{1}{2} miles

Step-by-step explanation:

2 \frac{2}{4} + 2 \frac{3}{4} = 4 \frac{5}{4} which equals 4 + 1 \frac{1}{4} or 5 \frac{1}{4}

5 \frac{1}{4} + 3 = 8 \frac{1}{4}

she ran 8 and one-quarter miles in the first week and if she ran the same amount the second week then we can add to get the answer:

8 \frac{1}{4} +  8 \frac{1}{4} = 16 \frac{2}{4} or 16 \frac{1}{2}
