180°=2x+10x+12
180=12x+12
168=12x
x=14
angle J=2x
J=2(14)
J=24
angle K=10x+12
K=10(14)+12
K=140+12
K=152
therefore, answer is C.

17=17 Correct :)
Answer:
15 y 8
Step-by-step explanation:
y = x - 7
x² + y² = 289
sustituir: x² + (x - 7)² = 289
distribuir: x² + x² - 14x + 49 = 289
sustraer + simplificar: 2x² - 14x - 240 = 0
dividir: x² - 7x - 120 = 0
x² - 15x + 8x - 120 = 0
(x - 15)(x + 8) = 0
x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales
sustituir: y = 15 - 7
simplificar: y = 8
Answer:
