Answer:
A
Step-by-step explanation:
Because 45 + 2x = 180 divide it by 2 gives 4
Answer:70;20
Step-by-step explanation:
P(B) = 2/15
The area of rectangle A is 5(7) = 35 in².
The area of rectangle B is 3(4) = 12 in²
The area of square C is 4(4) = 16 in²
The area of rectangle D is 3(9) = 27 in²
The total area of the figure is 35+12+16+27 = 90 in².
The probability of hitting B is 12/90 which simplifies to 2/15.
30 is greater than 3. So 30 > 3
