Question

MZa=20x + 7 and mZb= 5x – 2. What is the value of x

a) x = 5
b) x = 4
c) x = 3
d) x = 2

Answer 1

To find the value of x, set the two given equations equal to each other, simplify the equation, and solve for x.

Step-by-step explanation:

To find the value of x, you need to set the two given equations equal to each other:

mZa = mZb

20x + 7 = 5x - 2

Next, you can simplify the equation by subtracting 5x from both sides:

15x + 7 = -2

Then, subtract 7 from both sides:

15x = -9

Finally, divide both sides by 15 to solve for x:

x = -9/15

Therefore, the value of x is -9/15 or approximately -0.6.
