Question

If angle 4 equals 3x - 7 and angle 5 equals 9x - 43, find x.

a) x = 5
b) x = 7
c) x = 10
d) x = 12

Answer 1

To find x, set angle 4 equal to angle 5 and solve for x.

Step-by-step explanation:

To find x, we can set angle 4 equal to angle 5.

So, 3x - 7 = 9x - 43.

Subtracting 3x from both sides gives us -7 = 6x - 43.

Adding 43 to both sides gives us 36 = 6x.

Dividing both sides by 6 gives us x = 6.

Therefore, the value of x is 6.
