Question

Plz help fast i dont now how to do this and it is near impossible

Answer 1

Hello!

Since the angles are alternate interior angles they equal each other

5x - 28 = 3x + 12

Now you solve this algebraically

5x - 28 = 3x + 12

Subtract 3x from both sides

2x - 28 = 12

Add 28 to both sides

2x = 40

Divide both sides by 2

x = 20

Now we put x into the equation we are wanting to find out

5x - 28

5(20) - 28

Multiply

100 - 28

Subtract

72

The answers are x = 20 and 5x - 28 = 72°

Hope this helps!
