Answer:

x = 13.5

Step-by-step explanation:

Since we know that all angles of a triangle add up to 180 degrees, we can form the following equation:

23 + 23 + 10x - 1 = 180

10x + 45 = 180

10x = 135

x = 13.5

X= 13.5

Every triangle equals 180 degrees. 23+23= 46. 46 - 1= 45. Then you solve the equation 10x+45=180 which would equal, 13.5.
