1) Striangle = 1/2 * (12-8) * 4 = 1/2 * 4 * 4 = 8 km^2
2) Srectangle = 4 * 8 = 32 km^2
3) Sfigure = 8 + 32 = 40 km^2
Number C
Answer: x=7
12x-4=0.5(22x+6)
12x-4=11x+3
-11x -11x
x=7
Explanation: use the tangent-chord angle theorem.
Answer:
It is the distance of x from zero. Examples:The absolute value
