Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
The number is 'n'.
Five times the number is 5n .
Nine more than that is 5n + 9 .
7 - 2 (7) -8
7 - 14 - 8
7-14= -7
-7 - 8 = - 15
