Answer:
C
Step-by-step explanation:
∠1 = 3x + 18 {Vertically opposite angles}
∠1 + 28° = 90
3x + 18 + 28 = 90
3x + 46 = 90
3x = 90 - 46
3x = 44
x = 44/3

Answer:
20,4
Step-by-step explanation:
Suppose that x, y are the the length and width
Area=x*y=80
Parameter=2(x+y)=48....x+y=24
Xy=80...x(24-x)=80...x=20,y=4
Answer:
(1,16) (2,32) (3,48) (4, 64) (5, 80) (6,94)
Answer:
a) Peter:$400
b) John received more than Peter
Step-by-step explanation:
john:Jane:Peter:James
7:1/4(0.25):5:8
7+0.25+5+8 = 20.25
Jane
$1,800 × 0.25 ÷ 20.25 =$200
$1,800 - $200 = $1,600
20.25 - 0.25 = 20
Peter
$1600×5÷20= $400
John
$1600×7÷20=$560
