Question

Help¡¡ i dont understand

Answer 1

x = 21 2/3

Explanation:

Corresponding angles are equal

So

6x - 20 = 3x + 45

3x = 65

x = 21 2/3

or

x = 21.67

Answer 2

x = 65/3

Explanation:

These angles are corresponding angles, Corresponding angles are equal if the lines are parallel

Assuming the lines are parallel

6x-20 = 3x+45

Subtract 3x from each side

6x-3x-20 = 3x-3x+45

3x-20 = 45

Add 20 to each side

3x-20+20 = 45+20

3x = 65

Divide by 3

3x/3 = 65/3

x = 65/3
