Answer:
45
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
2x - 12 + 2x + 17 + 9x - 7 = 180 add like terms
13x - 2 = 180 add 2 to both sides
13x = 182 divide both side by 13
x = 14
m<X = 2x + 17 replace x with 14
2*14 + 17 = 45
Answer:
a) 6 17/20
b) 10 31/60
Step-by-step explanation:
a) 9 2/20 - 2 1/4 = 137/20 = 6 17/20
b) 6 17/20 + 3 2/3 = 631/60 = 10 31/60

2x-12=2y
2. Divide both sides by 2
x-6=y
