Mathematics
1 answer:
Afina-wow [57]3 years ago
6 0

Answer:

Step-by-step explanation:

Since B is the midpoint, AB must be equal to BC.

AB = BC

7x - 4 = 3x + 32

Isolate the variable

7x - 4 = 3x + 32

4x = 36

x = 9

Now solve for one side.

AB = 7x - 4

AB = 7(9) - 4

AB = 59

Since both sides are equal, finding AC just means multiplying one side by 2.

AC = AB * 2

AC = (59) * 2

AC = 118

You can double check by finding the other side and multiplying by 2.

BC = 3x + 32

BC = 3(9) + 32

BC = 27 + 32

BC = 59

AC = BC*2

AC = 59*2

AC = 118

m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°

<h3>How to determine the angles</h3>

It is important to note that the sum of angles in a triangle equals 180°

The given structure is a triangle, thus, the angles sum up to 180°

m ∠ A + m ∠ B + m ∠ C = 180°

m∠ A = 60°

m ∠ B = 60°

m ∠ C = 60°

The sum of the angle in the triangle = 60° + 60° + 60° = 180°

Thus, m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°
