Answer:
x = 3
Step-by-step explanation:
Simplify 2(x+12)
6x+12=2x+24
Move all terms containing x to the left side of the equation. 4 x + 12 = 24
Move all terms not containing x to the right side of the equation. 4 x = 12
Divide each term by 4 and simplify. x = 3
picture is blurry but if they are similar find the scale between the known sides
smaller triangle bottom looks like it says 8?
the larger one is 16
8/16 = 0.5 so the smaller one is half the size of the larger one
so half of 8 is 4 so y = 4
since they are similar the angles would stay the same so angle B would be the same as s which is shown as 27 degrees.
In 12 years she will be X+12
