Answer:

x = 20

Step-by-step explanation:

The angles are vertical angles which means they are equal

x+40 = 3x

Subtract x from each side

x+40-x = 3x-x

40 = 2x

Divide by 2

40/2 = 2x/2

20 =x

Answer:

Step-by-step explanation

x1 = 2, y1 = -2 and m = 3/4

y - y1 = m(x - x1)

y - (-2) = 3/4(x - 2)

y + 2 = 3/4(x - 2)

Multiply each term by 4

4y + 8 = 3(x - 2)

4y + 8 = 3x - 6

4y = 3x - 6 - 8

4y = 3x - 14
