Left side angle = 180-150-12 = 18 degrees
10 / sin 12 = c / sin 18
c = 10 * sin 18 / sin 12
c = 14.9 cm to nearest tenth
You have to set up to equations
EQ 1: x-2=2 EQ 2: x+2=2
Solve for x and see which value fits the conditions, in this case 4
1st number = x, 2nd number = y
Translating the question mathematically it becomes:
x-2 = 3y, or to make it easier: x= 3y+2, x+y= 22
Thus:
(3y + 2) + y = 22
4y + 2 = 22
Move the 2 on the other side, changing its sign to negative:
4y = 22 - 2
4y = 20
Divide by 4, to obtain only y:
4y : 4 = 20 : 4
y = 5
To obtain x:
x= (3*5) + 2= 15+2 = 17
Verify it: 17+5=22
Answer:
the probability is closer to 1 than it is to 0
