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.
Y2 + x2 = 53
y − x = 5
y = 5 + x
(5+x)^2 + x^2 = 53
(5+x)(5+x) + x^2 = 53
25 + 10x + x^2 +x^2 = 53
2x^2 + 10x - 28 = 0
(x-2)(x+7)=0
x = 2 , x = - 7
y = 5 + 2
y = 7
y = 5 +(-7)
y = 5 - 7
y = - 2
Answer:
x=10/3=3.333 or = - 10/3=-3.333
