Question

How do I solve for X?

Answer 1

Answer:

x = -9

Step-by-step explanation:

The top angle would be 90 degrees due to the square.

The angles of a triangle add up to 180 degrees.

Set up the equation:

90 + 45 + x + 54 = 180

189 + x = 180

Subtract 189 from both sides:

x = -9

Now, if you need to solve for the angle, just plug x in:

-9 + 54 = 45 degrees

(In your case it is just looking for x so it would be x = -9)
